WordPress sets its memory limits within the wp-settings.php file. All that has to be done is change the memory limit from “32M” to “64M”.
Here are the step by step instructions:
- Open wp-settings.php in your favorite code editor. This file is in the root directory of your WordPress installation
- Go to line #13 of wp-settings.php and locate ’32M’
- Change the “32″ to “64″
- Save the file and FTP it to your server
