You’re working on your WordPress site, everything’s running smoothly, and then—boom! The dreaded “max_execution_time” error strikes, halting your progress. It’s like your site has decided to tap out, leaving you stuck and frustrated mid-task. 😓
This error happens when a script takes longer to execute than the server allows, essentially timing out and preventing your process from completing. But don’t worry—you’re not alone in facing this!
In this guide, we’ll not only explain what causes the max_execution_time error but also show you how to fix it with easy-to-follow steps. No need to worry about technical complexities—we’ll walk you through simple solutions to get your site back on track.
Let’s dive in!
What Is the max_execution_time Fatal Error?
You might be wondering, what’s this max_execution_time all about? In simple terms, it’s WordPress’s way of saying, “Hey, I’m running out of time to complete this task!” Basically, every script has a time limit, and when WordPress reaches that limit, it throws up this error.
The max_execution_time is a server setting that restricts how long a script can run before being cut off. When a process—like a plugin update or a theme installation—exceeds this time, you’re hit with the fatal error.
This timeout feature is actually designed to protect your server from getting overwhelmed by scripts that take too long to execute. However, it can also be a major headache, especially when you’re running necessary operations on your site.

What Causes max_execution_time Fatal Error?
Let’s get to the bottom of this error—whether it’s a heavy WordPress plugin, a slow server, or something else entirely. We’ll explore the most common reasons for the max_execution_time error and why it suddenly interrupts your smooth WordPress experience.
Heavy Plugins or Themes
Some plugins or themes require more resources and time to run, especially if they involve large amounts of data processing. For example, a plugin designed to handle large image galleries or complex data can slow down your site, eating up the maximum execution time quickly. The heavier the plugin, the higher the chances of hitting this error.
Slow Server Performance
If your hosting server doesn’t have enough power or bandwidth to handle certain tasks, this can lead to timeouts. Shared hosting plans, in particular, often limit server resources, meaning your site may struggle to perform intensive processes. This becomes more evident when multiple users are drawing resources from the same server.
Bulk Operations
Running large imports, backups, or updates can trigger this error if the process exceeds the set time limit. Tasks like updating WordPress plugins for an entire website, migrating content, or restoring a backup file can all take longer than expected, especially on underperforming servers. These tasks can be data-heavy, stretching execution time past the limit.
Default PHP Settings
The server’s default PHP settings might not be optimized for WordPress and could limit script execution time too much. Many hosting providers set conservative limits to prevent the overuse of server resources, but this can backfire when running WordPress sites that require more flexibility. If the limit is set too low, even simple processes can cause this error to occur.
How to Fix the max_execution_time Fatal Error
There are several methods to fix this error, depending on your level of access to your server and comfort with editing files. We’ll go over the simplest solutions first, and you can choose the one that works best for you.
Method 1: Edit Your PHP.ini File
The PHP.ini file is a configuration file that controls how PHP on your server behaves. Here’s how you can modify it to increase the max_execution_time:
Step 1: Locate the PHP.ini file on your server. It’s typically found in the root directory or a folder named “config,” depending on your hosting setup.
Step 2: Open the PHP.ini file using an FTP client or your hosting control panel’s file manager.
Step 3: Find the line that reads: max_execution_time = 30
Step 4: Change the value from 30 to 300 (or any other suitable number based on your needs).
Step 5: Save the changes and re-upload the file to your server.
Step 6: Restart your server (if required by your hosting provider) to apply the new settings.
This method works for most users because it gives direct control over script execution times, which is helpful for larger or resource-heavy tasks.

Method 2: Modify the .htaccess File
The .htaccess file is a configuration file used by Apache servers that allows you to override certain settings, including the max_execution_time. Here’s how you can do it:
Step 1: Locate your .htaccess file in the root directory of your WordPress site.
Step 2: Open the file using an FTP client or your hosting control panel’s file manager.
Step 3: Add the following line of code:
php_value max_execution_time 300
Step 4: Save the file and re-upload it to your server.
Step 5: Clear your browser cache and refresh your site to see if the error has been resolved.
Be cautious when editing the .htaccess file, as errors here can cause server issues. Always create a backup before making any changes.

Method 3: Fixing it via wp-config.php
You can also adjust the max_execution_time directly in your wp-config.php file. This method is quick and doesn’t require much server access.
Step 1: Locate the wp-config.php file in the root directory of your WordPress installation.
Step 2: Open the file using an FTP client or your hosting control panel.
Step 3: Add the following line of code right before the line that says “That’s all, stop editing!”:
set_time_limit(300);
Step 4: Save the changes and upload the file back to your server.
This method is effective and doesn’t require as much access as modifying server files. It works well for users with limited control over server settings.

Method 4: Contact Your Hosting Provider
If you don’t have access to server files or are unsure about making changes yourself, contacting your WordPress hosting provider is a great option.
Step 1: Reach out to your hosting provider’s support team through email or live chat.
Step 2: Request them to increase the max_execution_time value on your server. A typical request would be to increase it to 300 seconds or more, depending on the needs of your site.
Step 3: Wait for confirmation from your hosting provider, then test your site to ensure the error is resolved.
Hosting providers are usually quick to make this adjustment for you, especially if you’re on a managed hosting plan. Managed services often handle such technical tasks seamlessly, preventing you from running into this issue in the future.

Method 5: Using A Plugin
The beauty of WordPress lies in its vast plugin library, offering solutions for virtually every problem—including fixing the max_execution_time error. For this method, we’ll show you how to use a plugin that increases both the execution time and upload file size, which can often be related issues.
Step 1: Install the Plugin
Begin by navigating to the WordPress admin dashboard, clicking on Plugins, and selecting Add New from the menu.
In the search bar, type in the name of the plugin, such as “Increase Maximum Upload File Size | Increase Execution Time.” Once you find the plugin by CodePopular, click Install Now, and activate it.
Step 2: Configure the Execution Time
After activation, locate the new settings under Media > Increase Upload Limit. Here, you’ll see detailed information about your WordPress configuration, including PHP version, current execution time, and file upload limits.
To resolve the execution time error, simply enter a higher value—like 300—into the Maximum Execution Time field. If you’re dealing with large media files, this plugin also allows you to increase the upload limit simultaneously. After making your adjustments, hit Save Changes and test your website to ensure the error is gone.
This method is especially convenient for users who aren’t comfortable editing code directly but still want a quick and effective fix.

Pro Tips for Avoiding max_execution_time Fatal Errors in the Future
Dealing with the max_execution_time error once is frustrating enough, so it’s a good idea to take proactive steps to avoid running into it again. By following a few best practices, you can minimize the risk of this error and keep your WordPress site running smoothly. Here’s how:
Keep Your Plugins and Themes in Check
Heavy plugins and themes can significantly impact your site’s performance, increasing the likelihood of hitting the max_execution_time limit. Plugins that require substantial resources, such as those managing large databases or running complex scripts, can eat up execution time quickly. Similarly, bulky themes with lots of additional functionality or features can slow things down.
How to Optimize:
- Regularly audit your installed plugins and themes, removing any that are unnecessary or outdated.

Frequently Asked Questions (FAQs)
Can increasing max_execution_time harm my site?
Let’s break the myth: increasing the max_execution_time will not harm your site under normal circumstances.
However, it’s essential to avoid setting it too high, as that could lead to excessive server resource usage, especially on shared hosting plans. The key is finding a balanced value that suits your site’s needs without overburdening your server.
For most WordPress sites, increasing the time slightly (to 300 seconds, for example) is safe and effective.
Is there an ideal max_execution_time value?
While every site is different, the general recommendation for most WordPress sites is to set the max_execution_time between 120 and 300 seconds. This range is long enough to accommodate most resource-heavy tasks, such as updates or large file uploads, without causing unnecessary delays or server strain.
If you find your site still struggling, it might be worth investigating the underlying cause, such as optimizing plugins or upgrading your hosting plan.
What should I do if none of the fixes work?
If you’ve tried adjusting your PHP settings, modifying the .htaccess or wp-config.php files, and even reached out to your hosting provider, but the error persists, it might be time to seek expert help.
Contact a professional WordPress developer or your hosting support team to dig deeper into the issue. Sometimes, the problem could stem from server limitations, improper configurations, or a plugin conflict that requires a more advanced solution.
