How to Fix the WordPress Memory Limit Error?

Unlike several common WordPress errors, the WordPress memory limit issue is quite easy to troubleshoot.

While you have exhausted the PHP memory limit on your site, mostly there are only two ways to fix the error. Either increase the PHP memory allotted to your site or upgrade your current hosting plan.

Increase the PHP Memory Allotted to Your Site

While your website runs out of memory, the simplest method to resolve WordPress memory limit error is to increase the memory of your site.

It is obvious that you can increase the memory limit depending on your hosting provider and plan. However, we will discuss about this aspect in next section.

To increase the memory limit, you will have to edit the wp-config.php file on your WordPress site. You will need an FTP client like FileZilla to locate and edit his file. 

Once you have installed FileZilla and set up the connection with your server, you need to find your site’s ‘root’ folder, which is usually either named after your site’s domain or is called public_html or www. Open that folder and search for a file named wp-config.php

The wp-config.php file stores specific information regarding your website’s database and settings. Hence, you mustn’t modify anything except a particular line of code which we will be looking up next.

In fact, it’s an ideal idea to make a backup of your website prior to making any changes to the file.

Now, as you did the backup, you can open up your wp-config.php file.

Then, search for the following line:

define( 'WP_MEMORY_LIMIT', '256M' );

This code will increase the PHP memory limit to 256MB.

Once the code is pasted, you need to save changes and upload the file back to the server and try to repeat those actions while you first saw this WordPress memory limit error.

You can check if the memory exhausted error is fixed. If the issue persists, then it means you still have the WordPress memory limit error. Try the second method to resolve this issue.

Upgrade Your Site’s Hosting Plan

If you are on a shared hosting plan, you likely need to upgrade to a Managed VPS Hosting or Dedicated Server UK, both of which offer additional space and resources.
