PHP memory limit is the maximum amount of memory that PHP scripts are allowed to use on a server. When you run a WordPress website, it requires a certain amount of memory to function properly.
If the website exceeds the PHP memory limit, it will result in errors and crashes.
Several factors can cause the PHP memory limit to be exceeded, such as using poor-quality plugins, running large scripts, or having a lot of media content on your website.
To identify if you are facing a WordPress memory limit error, use the Site Health tool available in the WordPress dashboard.
This tool can help you identify issues with your website, including memory limit issues. It can also provide you with recommendations on how to fix the issues.

How to Increase PHP Memory Limit in WordPress?
Increasing the PHP memory limit is another way to fix memory limit issues. Methods to increase the PHP memory limit in WordPress:
- Increasing PHP Memory Limit via wp-config.php
- Adjusting PHP Memory Limit via .htaccess
- Modifying PHP Memory Limit via php.ini
- Utilizing Server and Hosting Settings
It is recommended to increase the memory limit to at least 256MB to ensure that your website can handle larger scripts and media content.
Method 1: Increasing PHP Memory Limit via wp-config.php
One of the easiest ways to increase the WordPress PHP memory limit is by editing the wp-config.php file. This file is located in the root directory of your WordPress installation.
Before making any changes to this file, it is recommended that you create a backup copy.
To increase wp memory limit, you will need to add the following line of code to the wp-config.php file:
define( 'WP_MEMORY_LIMIT', '256M' );
define('WP_MAX_MEMORY_LIMIT', '256M');
This code sets the PHP memory limit to 256 megabytes. You can increase or decrease this value as needed. For instance, if you want to increase it to 512m, then you’ll have to use this code – define( ‘wp_memory_limit’, ‘512m’ );
It is important to note that this method may not work on all hosting environments. If you are unable to increase the PHP memory limit via the wp-config.php file, you may need to contact your hosting provider for assistance.
Method 2: Adjusting PHP Memory Limit via .htaccess
If you want to increase the PHP memory limit for your WordPress site, you can do so by editing the .htaccess file.
The .htaccess file is a configuration file that controls how your website behaves on the server. You can use it to modify various settings, including the Elementor memory limit.
To adjust the .htaccess memory limit, follow these steps:
- Connect to your website using an FTP client like FileZilla.
- Locate the .htaccess file in the root directory of your website.
- Download a copy of the .htaccess file to your computer as a backup.
- Open the .htaccess file in a text editor.
Add the following line of code to the file:
php_value memory_limit 256M
- Replace “256M” with the desired memory limit. You can set it to any value that your hosting provider allows.
- Save the .htaccess file and upload it to your website.
Once you have made these changes, the PHP memory limit for your WordPress site will be increased. You can check the current memory limit by installing a plugin like WP Memory Usage.
It is important to note that not all hosting providers allow you to modify the PHP memory limit via .htaccess. If you are not sure whether your hosting provider allows it, you should contact their support team for assistance.
In addition, modifying the PHP memory limit via .htaccess may not work for all scripts. Some scripts may override the memory limit set in .htaccess, so you may need to modify the memory limit in the script itself.
Overall, adjusting the PHP memory limit via .htaccess is a simple and effective way to increase the memory limit for your WordPress site. It can help improve the performance of your site and prevent memory-related errors.

Method 3: Modifying PHP Memory Limit via php.ini
If you want to increase the PHP memory limit for your WordPress website, you can modify the php.ini file. The php.ini file is a configuration file for PHP that contains various settings, including the memory limit.
Here’s how you can modify the PHP memory limit via php.ini:
- Locate the php.ini file: The location of the php.ini file varies depending on your server configuration. You can find the location of the php.ini file by creating a PHP file with the following code:
<?php phpinfo(); ?>
- Upload the file to your server and access it via your web browser. Look for the “Loaded Configuration File” section to find the location of the php.ini file.
- Open the php.ini file: Once you have located the php.ini file, open it in a text editor.
- Find the memory_limit setting: Use your text editor’s search function to find the memory_limit setting in the php.ini file.
Increase the memory limit: Change the value of memory_limit to the desired memory limit. For example, if you want to increase the memory limit to 256MB, change the value to:
memory_limit = 256M
- Save the php.ini file: Save the changes to the php.ini file and upload it to your server.
- Verify the new memory limit: To verify that the new memory limit has been applied, create a PHP file with the following code:
<?php phpinfo(); ?>
- Upload the file to your server and access it via your web browser. Look for the “memory_limit” setting to verify that the new memory limit has been applied.
Remember that modifying the php.ini file may not work on all hosting environments. If you are unable to modify the php.ini file, you can try increasing the memory limit via other methods, such as modifying the .htaccess file or using a plugin.
Method 4: Utilizing Server and Hosting Panel Settings
If you are using shared hosting, your hosting provider may have set a limit on how much memory you can use. However, some hosting providers allow you to increase your PHP memory limit through their control panel or by contacting their support team.
If you can access cPanel, use the MultiPHP INI Editor to increase your PHP memory limit.
Navigate to the “Software” section and click “MultiPHP INI Editor.” From there, select the domain you want to modify and adjust the memory limit value to your desired limit.
If you are on a shared hosting plan and do not have access to cPanel, you can try contacting your hosting provider’s support team to request an increase in your PHP memory limit. Some hosting providers may be willing to increase your limit upon request.
If you are on a dedicated server or have root access to your server, you can adjust the memory_limit value in your php.ini file.
However, it is important to note that making changes to your server settings can be risky and should only be done by experienced users.
Overall, utilizing server and hosting settings can be an effective way to increase your PHP memory limit.
Whether you have access to cPanel or need to contact your hosting provider’s support team, there are options available to help you increase your limit and improve the performance of your WordPress site.
