ok how do u try devmap mode to see if that it...
Ask someone with rcon access to the server. They could conceivable create a command to devmap certain maps, but I doubt they will just so people can screw around on them
if "Not all servers have !layout at level 5." is the case what level then?
I'm not positive about !layout, but all other ! type commands can be manually configured to allow/disallow admin levels to access them. You would need to ask the server operator what admin level is allowed access to !layout.
