    Hello @ericcool

    Thank you for your inquiry and I’m happy to assist you with this.
    I am not quite sure what do you mean by

    Wp_options is not cached

    wp-options cannot and should not be cached.
    By default, WordPress stores transients in your wp_options table with autoloading set to ‘yes’.
    When you install Memcached, your transients are now stored in your object cache but your old transients are still in wp_options. To fix this, run the following SQL:
    delete from wp_options where autoload = 'yes' and option_name like 'transient%';
    In Performance>Object Cache there is an option to Enable caching for wp-admin requests.
    It’s not advisable to this as it may cause side-effects, and possibly those are the transients in wp-options if wp_admin requests are not cached.
    Thanks!
