I'm having some difficulties having clients adding/editing categories within entries.
As the Super Admin, I can simply open an entry, click Categories and can add/edit categories without any troubles. When I log in as an Admin account type however, I am unable to add categories. When I click the link, I get two JS errors, one being a 500 Internal Server error, the other, "Uncaught ReferenceError: $loading is not defined."
Any ideas as to why this is not affecting Super Admins, but only the Admins?
We're using EE 2.5.3. Any help would be greatly appreciated!
