TTT weapons pack not working

Hello. I am using the TTT Weapon Pack for Servers. And I can’t figure out how to install it on my server. I downloaded it, extracted the GMA files and put the contents in my server addons folder. There are no errors, but no weapons spawn and the traitor/detective weapons are not in the equipment menu. Is this pack outdated, or am I doing something wrong?
Thanks!

Are you running your server on linux?

Yea. Ubuntu 14.04.

Does your folder have any capital letters in the name? If so, make them lowercase

That fixed it. Thanks!
