Garry's mod chat not working

Hello

When i start my Garry’s mod on srcds and i load normally and when i am up and i go into the chat by pressing y i type in and hit enter and nothing happened this is the same for everyone who joins my sever nor will it work on the console when i enter say <text> this also happens on single player but not on other severs

Is there any help on this?

Thanks, James

p.s it does the same when there are no add-ons or admin mods and i have contacted steam support and they said to come here!
