You need to specifically expand the memory if WordPress Fatal error is out of memory. Mostly 64 MB is more than sufficient. However, in certain cases, you may need to run more PHP scripts. So, you need to expand the PHP memory size.

To check the memory limit, you need to access your WordPress dashboard. Then you must browse for the option “Tools”. Go for the option “Site Health” and click “Info”. You can tap on the tab “Server” and check the PHP memory limit entry.

In the same place itself, you can check the details such as PHP time limit and PHP version. Now, if you have your memory limit below 64, please expand your limit. Here we will discuss the two methods:-

• Manually expand the PHP Memory

For this, you need to modify the two files wp-config.php. and .htaccess manually. However, if you make changes to the .htaccess file of WordPress installation you may end up with site-wide errors. It is because this file identifies how your file interacts with the server.

wp-config.php is one of the safest options to expand the memory limit of PHP. You may require SFTP (Secure File Transfer Protocol) client like FileZilla.

When you access your site using SFTP, open the root folder and check for the wp-config.php file.

Use the text editor. Once you do it, you may witness something like this:-

You can simply add the single code line after the <?php tag.

Please ensure to add the below line code.

define( ‘WP_MEMORY_LIMIT’, ‘XXXM’ );

Make sure to replace the variable “XXX” within this line itself to expand the memory. You can even double or set your PHP memory limit to 256 MB. Write the following code:-

define( ‘WP_MEMORY_LIMIT’, ‘256M’);

Now, if you are clear with the number, save these wp-config.php changes and close your editor.

Visit the dashboard of your WordPress and tap the option “Tools”. Next, go for the option “Site Health” and tap the button “Info”. Lastly, click the tab “Server”.

In most scenarios, manually declaring the PHP memory limit will not work. It is because it does not have essential permission to change the value. If you cannot manage to make changes to the PHP memory limit manually, please try the next option.

• Upgrading the hosting plan of your Website

Employing a decent WordPress hosting provider will fix the Fatal error that is allowed for the memory size of WordPress. If you encounter this trouble, make sure to upgrade for a better hosting plan.
