 * Sometimes, the add to cart function runs on a 500 error, when using Redis. The
   issue is that the plugin temporary stores cart item key on get_option(‘xoo_cp_added_cart_key’),
   set_option(‘xoo_cp_added_cart_key’) and its cached by Redis.
    Flusing Redis solves
   the issue.
 * Is there any other way to save that option temporary (like session or something),
   as wp_options is bad practice
