Gamemode problems somehow involving my game cache

When i joined a SSTRP server, the hud wasn’t the way it was before, it was the plain old hl2 hud instead of one it was supposed to be, i also went on a TTT server and the hl2 hud was still there.
I asked how I could fix it and they said clear my cache but I don’t know what they mean. Please help.

Edit: Just delete this thread, i forgot they had a help and support sub forum.

Delete the contents of your cache folder in your garrysmod directory.
