Introduction:

WordPress is a powerful content management system, but it can sometimes run into memory problems. This can happen when you have a lot of plugins installed, or when you’re trying to upload a large file. If you’re experiencing memory errors, you can increase the memory limit in PHP to fix the problem.

How to Increase Memory Limit in PHP via wp-config.php:

The easiest way to increase the memory limit in PHP is to edit your wp-config.php file. This file is located in the root directory of your WordPress installation.

To edit your wp-config.php file, you’ll need to use a file transfer protocol (FTP) client or a file manager in your web hosting control panel. Once you’ve opened the file, look for the following line of code:

PHP
define(‘WP_MEMORY_LIMIT’, ’32M’);

Use code with caution. Learn more
content_copy
The number after the M in this line represents the current memory limit in megabytes. To increase the memory limit, you’ll need to change this number. For example, to increase the memory limit to 128 megabytes, you would change the line to read:

PHP
define(‘WP_MEMORY_LIMIT’, ‘128M’);

Use code with caution. Learn more
content_copy
Once you’ve changed the memory limit, save the wp-config.php file and upload it back to your server.

Testing the New Memory Limit:

Once you’ve increased the memory limit, you’ll need to test to make sure that it’s working. You can do this by trying to perform the action that was causing the memory error. If the error doesn’t appear, then the new memory limit is working.

Conclusion:

Increasing the memory limit in PHP is a simple way to fix memory errors in WordPress. By following the steps in this blog post, you can increase the memory limit in your wp-config.php file and resolve any memory problems that you’re experiencing.
