Chat Won't Work

For some reason my server’s chat is somewhat broken… Things show up, but a player can’t type a message. Once you hit enter, the message just disappears. I was wondering if anyone else has had this problem. I’ve tried different gamemodes, and that’s not the problem. I did add Evolve, but the chat was working still after I installed it. I’m just confused… Help?

Is it a custom chatbox?

Just the default. I did try custom ones to see if it would fix. It’s not an appearance issue.

EDIT: Fixed. Just deleted a useless addon and it worked.
