After migrating a WordPress site, one of the most common and frustrating problems is dealing with broken links. These issues arise due to changes in the URL structure, domain name adjustments, or improper handling of internal links during the migration process.
Broken links can significantly impact your website’s functionality, leading to a poor user experience, reduced SEO rankings, and a loss of credibility with your audience. Therefore, it is crucial to address these issues promptly.
This guide provides step-by-step instructions on fixing these broken links, ensuring your website remains fully functional and accessible after migration. Whether you’re a WordPress developer, website owner, or content manager, this guide will help you maintain a seamless user experience.
WordPress Pre-Migration Best Practices
Before migrating a WordPress site, take certain precautions to ensure a smooth transition and prevent potential issues.
- Backup Your Website: Before starting site migration, it’s essential to create a complete backup of your website. A reliable backup ensures that you can restore your site if anything goes wrong during the migration process. Tools like BlogVault make it easy to back up your site automatically, offering a secure and dependable method to safeguard your data. By having a full backup in place, you protect your content, settings, and customizations from potential loss.
- Use a Staging Environment: Testing your migration in a staging environment is another crucial step to prevent issues from occurring on your live site. A staging site allows you to simulate the migration process and identify problems before they affect your users. With BlogVault, setting up a staging site is straightforward, as it provides a safe space to ensure everything runs smoothly before going live.
- Check for Hard Coded URLs: Hardcoded URLs within your website can cause significant issues during migration, as they may not automatically update to reflect changes in domain or URL structure. So, it’s important to identify and replace these hard coded links before migrating. Here, utilizing search and replace tools can help you to efficiently update these URLs, ensuring that your links function correctly post-migration.

Let our experts handle the process for you, ensuring your website remains fully functional and your links stay intact.
Causes of Broken Links Post-Migration
Understanding the common causes of broken links can help you fix them efficiently. Below are some of the main reasons why links often break after migration.
Change in URL Structure
When migrating a WordPress site, changes in the URL structure, such as switching from HTTP to HTTPS or altering the permalink settings, can lead to broken links. This often occurs when internal links don’t automatically update to reflect the new structure, causing them to break post-migration.
Incorrect Domain Mapping
Incorrect domain mapping happens when domain settings are misconfigured during migration. This misalignment can cause links to point to the wrong domain, leading to 404 errors. Ensuring that the domain is mapped correctly is essential to maintaining functional links.
Mismatched Site URL and Home URL
A mismatch between the site URL and home URL can occur during migration, especially when moving to a new domain or server. This discrepancy causes links to break because the URLs don’t match the correct structure needed for the site’s content to be accessed appropriately.
Incomplete Database Migration
An incomplete database migration occurs when not all data is successfully transferred to the new server or domain. This can result in broken links, as essential information that the links rely on may be missing or corrupted. Ensuring the entire database is accurately migrated is crucial to avoid these issues.
Changes in File Path Structure
During migration, changes in the file path structure can lead to broken links, particularly for media files and internal resources. If the file paths are altered without updating the corresponding URLs, the links may no longer point to the correct locations, resulting in errors when users try to access them.
Unchanged Internal Links
Unchanged internal links remain a common issue after migration, especially if the site’s URL or directory structure has changed. These links, still pointing to the old URLs, will break and lead to errors, as they are not automatically updated to reflect the new structure of the site.
Broken Redirects
Broken redirects often occur when existing redirects aren’t properly updated during migration. If the new URLs don’t match the old ones or if redirect rules are not correctly configured, users may encounter broken links, leading to a poor user experience and potential loss of traffic.

Incorrect .htaccess Configuration
The .htaccess file is crucial in managing URL redirects and server configurations. If this file is incorrectly configured during migration, it can result in broken links and redirect errors. Any misconfigurations in the .htaccess file can cause links to fail, leading to accessibility issues across the site.
Use of Old Caching Data
Using old caching data after migration can cause links to break because the cached version of the site may still contain outdated URLs or paths. This can lead to users being directed to incorrect or non-existent pages, causing confusion and broken links until the cache is cleared and updated.
Incomplete Plugin and Theme Updates
When plugins and themes are not fully updated during migration, it can lead to compatibility issues, including broken links. If the updates are incomplete, the site may reference old URLs or configurations that no longer exist, causing links within these plugins or themes to break and leading to functionality issues.

Identifying Broken Links After Migration
Identifying broken links after migration can be efficiently done using WordPress plugins like Broken Link Checker and Better Search Replace. These plugins automatically scan your website for broken links and help you address issues that may have occurred during migration.
Additionally, online tools such as Seahawk’s Broken Links Tool and Ahrefs offer comprehensive site audits, allowing you to detect and fix broken links across your entire site.
Manually identifying broken links involves using browser developer tools like Google Chrome Developer Tools and checking links via the WordPress admin dashboard. By inspecting the site through these methods, you can directly spot broken links or errors that may not have been updated correctly during the migration. These methods are precise and allow you to address specific issues that automated tools might miss.
Fixing Broken Links After Migration
After identifying the broken links and understanding their causes, the next step is to fix them. There are various methods available to address these issues, each tailored to specific causes. Below are some effective solutions you can apply depending on the underlying problem.
Use Search and Replace Plugins
A quick and efficient way to fix broken links is by using search and replace plugins like Better Search Replace. These plugins allow you to automatically find outdated URLs and replace them with the correct ones across your entire website, saving time and reducing the risk of human error.
Database Search and Replace
For a more in-depth fix, you can perform a search and replace directly within the database. This method involves running SQL queries to update old URLs with new ones. It’s particularly useful when dealing with large sites or complex migrations, ensuring that all instances of broken links are corrected.
Aggiornare i permalink
Updating your permalinks can resolve broken links that are caused by changes in your URL structure. Simply go to your WordPress dashboard, navigate to the Permalinks settings, and resave your preferred structure. This refreshes the permalink settings, which can help restore the functionality of your internal links.
Fix Media Links
Broken media links often occur when file paths change during migration, leading to missing images, videos, or other media files on your site. To fix these links, you can use plugins like Media File Renamer or Update URLs. These tools help you update media URLs across your site, ensuring that all images and media files are correctly linked.
Additionally, you can manually edit media URLs in the WordPress media library if the issue is limited to a few files. For bulk updates, these plugins streamline the process, automatically correcting paths based on your new directory structure.
Correct Serialized Data
Serialized data can become problematic during migration, especially when URLs are embedded within complex data structures like arrays or objects. Regular search and replace functions might break this data, so it’s crucial to use tools designed for this specific task.
Plugins like Search and Replace or WP Migrate DB allow you to safely search for and replace URLs within serialized data without causing corruption. These tools handle the serialization and deserialization process, ensuring that all instances of URLs within your database are updated correctly while preserving the integrity of your data.

Manually Updating Internal Links
For smaller websites or specific pages, manually updating internal links is a straightforward approach. You can edit each page or post directly through the WordPress editor, replacing old URLs with the correct ones. This method ensures precision, especially if you only need to update a limited number of links.
Edit the Database Directly with SQL Queries
Editing the database directly using SQL queries is a powerful way to update links site-wide, particularly when dealing with numerous broken links. By executing a search-and-replace query in your database, you can efficiently replace old URLs with new ones. Tools like phpMyAdmin or WP-CLI provide the interface and commands to perform these database edits safely.

Update the Site URL and Home URL
Sometimes, broken links can be resolved by simply updating the Site URL and Home URL in the WordPress dashboard. Navigate to Settings ⟶ General and ensure that both the Site URL and Home URL are set correctly. This update helps ensure all links point to the correct domain or subdirectory, particularly after a migration.
Regenerate .htaccess File
Regenerating the .htaccess file can fix issues related to broken links and redirects. You can regenerate this file by going to Settings ⟶ Permalinks in your WordPress dashboard and clicking “Save Changes” without making any modifications. This process refreshes the permalink structure and corrects any misconfigurations in the .htaccess file, restoring proper link functionality.
Dealing with Redirect Loops
Redirect loops occur when a URL redirects back to itself or creates an endless loop between two or more pages. This can be particularly tricky post-migration when redirects are misconfigured. To solve this, review your .htaccess file and any redirect rules set up within WordPress or plugins like Redirection.

Clear and Refresh Cache
After making changes to your links or URLs, it’s important to clear and refresh your website’s cache. Cached data may still contain old URLs, causing broken links even after they’ve been updated. Plugins like W3 Total Cache or WP Super Cache allow you to clear the cache, ensuring that users see the most up-to-date version of your site with all links functioning correctly.

Update Links in Theme Files and Plugins Manually
Sometimes, broken links are embedded within theme files or plugins. You need to manually update these by accessing the theme’s code or plugin settings. Use the WordPress theme editor or a file manager plugin like WP File Manager to locate and replace outdated URLs in the code, ensuring that all internal links within your theme or plugins point to the correct addresses.
Fix Image URLs with Media File Manager Plugins
When image URLs break after migration, you can use plugins like Media File Renamer or Regenerate Thumbnails to automatically update and correct the image URLs. These plugins help adjust file paths and regenerate media files if necessary, ensuring that images display correctly across your site without manually editing each link.
Use WP-CLI Commands for Bulk Updates
For advanced users, WP-CLI commands offer a powerful way to perform bulk updates to links directly from the command line. With WP-CLI, you can execute commands that search and replace URLs across your entire database, including within serialized data. This method is particularly useful for large-scale migrations where manual updates would be too time-consuming.
Correct Hard Coded Links in Custom Code
You need to manually update hard coded links in custom code to reflect the new URLs. This involves editing the code directly where the URLs are specified, often found in theme files, custom functions, or custom plugins. Using a code editor or the built-in WordPress theme editor, you can search for the old URLs and replace them with the correct ones, ensuring that all hard coded links function correctly after migration.

WordPress Post-Migration Testing and Verification
After migration, it’s crucial to test your website using browser and developer tools to ensure everything functions correctly. Tools like Google Chrome Developer Tools allow you to inspect elements, check for broken links, and identify any issues with the site’s performance. By manually navigating through your site, you can catch errors that automated tools might miss, ensuring a smooth user experience.
Once you’ve completed the initial testing, recheck your site with specialized plugins like Broken Link Checker and All in One SEO. These plugins scan your website for any remaining issues, including broken links, missing media, or SEO problems. Running these plugins after the migration provides an extra layer of assurance that your site is fully operational and ready for visitors.
Lastly, ongoing monitoring and maintenance are essential to keeping your WordPress site in top shape post-migration. Tools like UptimeRobot and WP Cerber can help you monitor your site’s performance and security, alerting you to any new issues that may arise. Regularly checking your site and updating your plugins and themes will help prevent problems and ensure your site remains healthy over time.
