# Cannot activate options, checkboxes disabled

 * After installing and activating APCu Manager there is a banner saying “APCu Manager
   has been correctly installed.”.
 * So, I go to the settings page to activate the object cache, but all the checkboxes
   are disabled and cannot be clicked. What could be the reason for that? Perhaps
   a conflict with another caching plugin? I have “Autoptimize” and “WP Super Cache”(
   by Automattic) installed.
 * Thank you in advance for your assistance!

 * That’s a valid question. I presumed so, but now that you ask, I need to check
   back with the hoster. Thank you for your feedback!
 * Cheers
