I have created a custom post type and called it 'videolibrary'. I then created a single-videolibrary.php page and put it in my custom theme root directory. When viewing the post, the single theme page is not working.
I think copied the exact same file into the Twenty Eleven theme and it works fine with that theme activated, and also works fine when copied into a different custom theme.
Any idea what could be preventing it from working in that particular theme?
