How to Move the Menu Item Under the Setting Menu
The menu item of WP Fastest Cache is added to the top level menu by default so you can reach the settings page of WP Fastest Cache very quickly.
But if it bothers you that the menu item is in the top level menu or you think it’s redundant, you have the flexibility to reposition the menu item to the Settings Menu.
You need to add the following lines after <?php which exists at the top of wp-config.php file.
define("WPFC_MOVE_MENU_ITEM_UNDER_SETTINGS", true);
