it seems to me, falco, that you have not updated your server.cfg with necessary server configs when you added your server to your installation (there's a link on your admin panel server list for said cvars). Or you missed a key step in the installation process.
// Paste the following text into your '/cfg/sourcemod.cfg' file,
// then change the map on the server
// SourceMod server settings
I could not get past the import amx bans so I exited.
