Gmod 13 Server ( ADDONS Come out ERRORS!)

Hello Face punch studio’s.

I have a dedicated server started completely fresh. I downloaded workshop.vdf to be able to add addons to my server. It seems it works but when I join the server it downloads all the items, but when im in the game the things i spawn come out as errors on everything. Tried it on 6-7 different addons to see if it was a game I was missing but nothing seem to go on the right track from there. Any help?

=================
Stuff I downloaded:

Space suit-
COD sniper model-
barney from hl1-
some sweps-
