Solving memory limit exhausted in PHP

This is the long walkthrough on how to fix this problem which is due to the fact that a too low memory limit is set in the PHP ini file.

1.) The ini file can be in different locations depending on your configuration so start with uploading and running a script looking like this to the server:

<?php
	phpinfo();

2.) Run the script in the browser and locate the php.ini location, it could for instance be: /etc/php5/apache2

3.) SSH into the remote server or do whatever it is you need to do to be able to edit the file.

4.) Open the file in nano: sudo nano /etc/php5/apache2/php.ini

5.) Use CTRL-W to search for memory_limit.

5.) Change the value to more than you already have, I read somewhere that 64MB is good for Wordpress for instance.

5.) CTRL-O (save) followed by CTRL-X (exit).

6.) sudo /etc/init.d/apache2 restart

Done! Phew…
