Solved Removing the new build limitations?

You don't place it in autoexec_default. You rename autoexec_default to autoexec.cfg. autoexec_default is not read by the server.

 

Ok then change it back to its original? Or i will have 2 autoexec.cfg

 

No you just need autoexec.cfg. The original, at least on my server, was autoexec_default which you then rename to autoexec.cfg and put in the console commands that you wish to be permanent in there

 

Ok I think I did it now but how do I know its working?

 

it also dephens on it what you're placeing inside of those files
so on the autoexec.cfg
you can add some mods from the steamworkshop,
and you can make people admin on it like this,

Addadmin [Steam64Id]

you can find thay steam64id on steamid.io
and on the no building stuff just give your self some stuff to place end when you will see the buildinglimit is not going up then you know its working
