Increase PHP Memory Limit

If your site is having memory limit issues, here are a few things you can try before contacting your host.

1. Edit wp-config.php

Add this line right before the line that says /* That's all, stop editing! */:

define( 'WP_MEMORY_LIMIT', '256M' );

WordPress memory can be different from the server memory — you need to set this regardless of server memory settings.

2. Edit php.ini

If you have access to your php.ini file, find the memory limit line and increase it:

memory_limit = 256M ; Maximum amount of memory a script may consume

3. Edit .htaccess

If you don't have access to php.ini, add this to your .htaccess file:

php_value memory_limit 256M

4. Contact Your Host

If none of the above works, contact your host and ask them to increase your PHP memory limit. Since you are paying for those resources, you should rightfully expect to be getting your money's worth.
