Why is this error coming to your website?

This error occurs as the PHP application processes are loading a massive amount of data that consume a large of RAM and memory resources that you have specified in the php.ini file via “memory_limit”.

Step 1: Locate the php.ini file

Let’s run the following command to locate the position of php.ini file

vi /etc/php.ini

Step 2: increase the value of memory_limit

We assume that currently, your memory_limit is 128M, you need to change memory_limit to double. For example:

Change from:

• If PHP is an apache module, then you run:

/etc/init.d/httpd restart

• If PHP works as PHP-FPM, let’s run:

/etc/init.d/phpfpm restart

Method 2: Change memory_limit from .htaccess file

In case, you don’t have the access authority to edit the php.ini file on your system, you can modify memory_limit with a .htaccess file. All you need to do is change as below:
