- Large media files
- Server-level limitations
Increasing Your PHP Memory Limit
The primary method to fix the WordPress memory exhausted error is by increasing the PHP memory limit. Below are several ways to achieve this:
Edit wp-config.php File
The wp-config.php file is a crucial configuration file for WordPress. To increase the memory limit, you can add the following line to this file:
define('WP_MEMORY_LIMIT', '256M');
This code attempts to increase the memory limit to 256MB, which is generally sufficient for most sites. Make sure to back up this file before making any changes.
Modify php.ini File
If you have access to your server’s php.ini file, you can directly modify the memory limit. Look for a line that starts with memory_limit and adjust its value:
memory_limit = 256M
After making these changes, save the file and restart your web server to apply the changes.
Using .htaccess File
If you’re on an Apache server, you can also try to adjust the memory limit by modifying the .htaccess file. Add the following line of code to this file:
php_value memory_limit 256M
As with other methods, be sure to back up this file before editing it.
Consult Your Hosting Provider
If the above methods don’t yield results, it might be time to consult your hosting provider. Some hosting services set specific memory limits that cannot be modified from your end. They may be able to increase the limit on your behalf or recommend a more suitable hosting package.
Optimizing Your WordPress Installation
Increasing the memory limit is only part of the solution. Another critical aspect is optimizing your WordPress installation to reduce memory consumption. Here are some effective strategies:
Deactivate Unused Plugins
Plugins can be a significant source of memory usage. It’s advisable to periodically review your installed plugins and deactivate any that you don’t use. Aim to keep only those that are essential for your site’s functionality.
Switch to a Lightweight Theme
If you’re using a resource-heavy theme, consider switching to a lightweight alternative. A theme that’s optimized for performance will ease the memory load on your server and improve load times.
Limit Post Revisions
By default, WordPress saves multiple revisions of each post, which can take up valuable memory. You can limit the number of revisions saved by adding this line to your wp-config.php file:
define('WP_POST_REVISIONS', 5);
This will ensure that only the last five revisions are saved for each post.
Advanced Techniques for Memory Management
For those who are comfortable with advanced techniques, consider implementing the following strategies:
Object Caching
Object caching can be beneficial in reducing memory usage by storing frequently-used data in the cache, lowering the load on your database. You can use plugins like Redis or Memcached to implement this effectively.

The WordPress memory limit error, commonly indicated by messages like “Allowed memory size exhausted,” can be a frustrating hurdle for website owners. This issue typically arises when a plugin or theme requires more memory than what is allocated to PHP by default. Understanding how to address this problem is crucial for maintaining site performance. Below, we outline effective methods to tackle these memory limit issues head-on.
Understanding the Memory Limit in WordPress
Every WordPress site operates under a specific PHP memory limit, which dictates how much memory can be consumed by scripts running on the server. By default, this limit is often set to 40MB for single sites and higher for multisite installations. When a site exceeds this allocation, it can result in fatal errors, thus hindering functionality.
Increasing the PHP Memory Limit
The most straightforward method to resolve the memory exhausted error is to increase the PHP memory limit. There are several ways to do this:
Editing wp-config.php File
One common method is to edit your site’s wp-config.php file. This file is located in the root directory of your WordPress installation. You can add the following line just before “That’s all, stop editing!” in the file:
define('WP_MEMORY_LIMIT', '256M');
This change will raise your memory limit to 256MB. Make sure to save the file after making adjustments. You may refer to more detailed instructions here.
Modifying php.ini File
If you have access to your server’s php.ini file, you can also adjust the memory limit there. Open the file in a text editor and locate the line that specifies `memory_limit`. You can change it to:
memory_limit = 256M
After saving the changes, restart your web server for the new settings to take effect.
Using .htaccess File
Another method involves the .htaccess file, typically located in your WordPress root directory as well. You can add the following line to increase the memory limit:
php_value memory_limit 256M
This method is especially useful if you do not have access to php.ini or if you are using shared hosting.
Disabling Unnecessary Plugins
Sometimes, the issue stems from poorly coded or resource-heavy plugins. Deactivating unnecessary plugins can free up memory and optimize your website’s performance. Review your current plugins and disable those that are non-essential or potentially problematic.
Switching to a Default Theme
If disabling plugins doesn’t resolve the issue, consider switching to a default WordPress theme. Sometimes themes consume excessive resources, resulting in memory exhaustion. By using a standard theme, you can determine if the theme is the culprit.
