1. Edit your wp-config.php file and enter something like:
define('WP_MEMORY_LIMIT', '1024M');
WordPress memory can be different to the server – you need to set this regardless of server memory settings

2. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 1024M:
memory_limit = 1024M ; 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: (You can use 1024 / 2048 / 4096 …)
php_value memory_limit 1024M
4. If none of the above works then talk to your host.
