FCVAR_SERVER_CAN_EXECUTE errors...

Hello. Today i was playin gmod untill i got strange errors like
FCVAR_SERVER_CAN_EXECUTE prevented server running command: toggleconsole
FCVAR_SERVER_CAN_EXECUTE prevented server running command: gameui_hide
I could’nt do ANYTHING. When admin kicked me for my request i got this server every time i pressed some button. I couldnt even quit gmod.
