ext_checker.php. I ran
ext_checker.phpand it ran fine. Found no issues. I can see that the Extensions category and module is installed in ACP > System > Module management > Administration Control Panel > Customise. Both the category and module are there and are enabled. But when I go to the Customise tab it doesn't show.
Frustrated I emptied the modules table and copied in the rows from the modules table on a source database on my local host running unaltered phpBB 3.2 (the forum is 3.2 as well). I purged the cache. Still not there.
I looked at my administrator permissions to see if I didn't have the acl_extensions permission. It shows I have all permission.
I even copied in the user_permissions column for the admin from my localhost database, purged the cache to see if it would appear. It doesn't.
