Most likely a caching issue. Go to Site Administration > Development and Purge All Caches.

Jon was/is correct in advice. 

Try direct URL to purge cache ...

https://yoursever/admin/purgecaches.php

If not logged on it will ask you to login and should forward you that screen.

But, if you can't get there via GUI, do you have ssh into your server?

IF so, manually 'purge the cache' by going to moodledata/cache then rm -fR * at that location ... make sure you are in moodledata/cache/ when executing a 'global all' like *.

No need to restart any service/server, just hit your moodle and login as an admin.

Fingers X'd!
