As far as I know you can't disable rcon, as it is built into the samp program. Check your script and see if there is anything that says "if(isplayeradmin)" because this will make it so only rcon admins can do whatever is next.

As for the wiki you read, that is talking about a remote console (so you can enter rcon commands without being in the server) and will probably not fix your situation.
