How to Increase the WordPress PHP Memory Limit

1. Edit your wp-config.php file and enter something like: This increases the WP memory limit for the front-end.

define('WP_MEMORY_LIMIT', '512M');

This increases the memory limit in wp-admin.

define( 'WP_MAX_MEMORY_LIMIT', '512M' );

2. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 64M try 256M or 512M:

memory_limit = 512M ; Maximum amount of memory a script may consume (64MB)

3. If you don’t have access to PHP.ini try adding this to an .htaccess file:

php_value memory_limit 512M

4. If none of the above works then talk to your host.
