If you get a blank white page or a plugin/theme wont load correctly for you or you have the message come up “WordPress Memory size exhausted” then this is the solution for you.

Go to your WordPress files located in your control panel of your host.
Go to the wp-config.php file and click edit
Add this line of text
/** Memory Limit */
Then click save and your done.
