GMod Addons not showing up on Sandbox?

I have loads and loads of addons installed. I even reinstalled them manually and deleted them from the addons folder in my garrysmod folder. Despite that, they still do not show up in my Q menu. Yes, I did check the Facepunch Support site and my date and time is correct. Are there any solutions you guys can recommend?

Read. Do what I asked the other person to do.

Well, I enabled addons and it seems it works for at least some addons. What I DON’T understand is how they became disabled in the first place.
