15+ Most Common WordPress Errors And How To Fix Them


Imagine working tirelessly on your WordPress site only to encounter an unexpected error that disrupts its functionality. Don’t let such setbacks derail your progress. In this guide, we’ll look at the common WordPress errors and provide actionable solutions so you can keep your site running smoothly and maintain user satisfaction.

WordPress White Screen of Death

The dreaded WordPress White Screen of Death (WSOD) can bring your site to a halt, displaying nothing but a blank page to your visitors. The WSOD can result from poorly coded plugins or themes, unreliable web hosting, or issues with PHP files. Identifying and fixing this error is pivotal for a seamless user experience and upholding your site’s reputation.


One of the common causes for WSOD is a plugin conflict or caching issue. Here are some steps you can take to troubleshoot the WSOD issue:

  • Clear your browser cache
  • Deactivate any problematic plugins
  • If the issue persists and an error message appears, consider replacing some of the WordPress core files.

However, if you still face difficulties despite attempting these methods, don’t hesitate to contact your hosting provider’s support team for further assistance.

500 Internal Server Error

The 500 Internal Server Error is another issue that can plague your WordPress site. It may be caused by various factors, such as:

  • Incorrect file permissions
  • An unresponsive PHP script
  • Heavy server load
  • Misconfiguration of ‘WordPress Address’ and ‘Site Address’ settings
  • Brute force attack.

Pinpointing the cause and executing the correct solution is fundamental to sustaining your site’s performance.


To address the 500 Internal Server Error:

  • Try reloading the page
  • Clearing your browser cache
  • Verifying DNS functionality
  • Disabling your CDN or firewall or contacting your hosting provider for assistance.

If these steps don’t resolve the issue, you might need to upgrade your hosting plan, optimize your site for speed, deactivate resource-intensive plugins, switch to the default WordPress theme, or increase the PHP memory limit.

Remember, a 500 Internal Server Error can also impact the WordPress admin dashboard, so promptly addressing this issue becomes vital.

Error Establishing Database Connection

A functional database is crucial for your WordPress site, and the “Error Establishing Database Connection” can disrupt your site’s functionality. This error occurs when WordPress cannot access its database, preventing users from accessing the WordPress dashboard. Comprehending the cause and executing a solution is vital for a seamless user experience.


Typical solutions for this common error include:

  • Verifying the database login credentials
  • Repairing the database
  • Reaching out to your hosting provider.

To verify your credentials, check the username, password, and hostname in your wp-config.php file and replace them if they’re incorrect. If the issue persists, consider activating WordPress’ automatic database optimization tool to rectify the Error Establishing Database Connection.

Troubleshooting Plugin and Theme Conflicts


Plugin and theme conflicts can cause various errors on your WordPress site, impacting its performance and user experience. Detecting and resolving these conflicts is key to the smooth operation of your site.

Initially, to troubleshoot any issues, follow these steps:

  • Deactivate any plugins and themes that may be causing issues
  • Check for compatibility issues and, as a last resort, use the default theme
  • If you cannot log in after installing a new plugin, consider deactivating the plugin.

Sometimes, you may need to temporarily disable all WordPress plugins by accessing the FTP and renaming the plugins folder.

Image upload issues can affect your site’s appearance, making it look unprofessional and deterring visitors. These issues are generally caused by incorrect file and directory permissions.

  • To fix image upload issues, start by verifying the file permissions.
  • Set the folder permissions for wp-content to 755 and all its subfolders as well. Also, set file permissions for all files inside them to 644.

If the issue persists, add the following code to your wp-config.php file to address the “Missing a Temporary Folder” error:

define (‘WPTEMPDIR’, dirname(__FILE). ‘/wp-content/temp/‘).

Don’t forget to create a new folder named ‘temp’ inside the wp-content folder as well.
