I am running a Moodle 2.5.2 on Windows Server 2008 R2, with PHP 5.3.19 installed. I am trying to get the APC Cache Plug in working to help improve performance. I have been following the kink in the Moodle Docs (as well as others) from here - http://docs.moodle.org/25/en/Installing_APC_in_Windows
As you will see from the attached pictures I have added the module but cannot get the PHP extension to load in order to be able to configure it in Moodle. I saved the required file for PHP 5.3 into the Ext folder and edited the PHP.ini, restarted and nothing. Is there something I am missing, any help would be greatly appreciated.
