[SOLVED] [Wordpress] Fatal error: Allowed memory size of 67108864 bytes exhausted

Open your wp-config.php which is located in the root WordPress directory. Then add the following line inside the main php tag:

define('WP_MEMORY_LIMIT', '96M');

This will increase the memory limit to 96M. This value depend on your need and the server coditions, you could use 32M, 96M, 128M, 256M, 512M, 1024M, 2048M, 4096M. Make sure your server allow you to use that much dedicated memory.
