You are creating a variable and trying to use it as a callback.
If you want to create custom callbacks, you'll have to forward and not initialize them
you shall do it like this:

Код:

forward OnPlayerOfflineLogin(name[]);
public OnPlayerOfflineLogin(name[])
{
	if( PlayerInfo[MAX_PLAYERS][pPermaBanned] == 3 || PlayerInfo[MAX_PLAYERS][pBanned] >= 1 )
	{
		SendClientMessage( playerid, COLOR_WHITE, "That player is banned" );
 	}
 	return 1;
}

NOTE: this code won't work like it is
You can not use "PlayerInfo[MAX_PLAYERS]..." the way you are using, you have to enter the ID you want to check not "max_players", cause that would be the number you've set to maximum players on your server.
It either has to be "PlayerInfo[playerid]" or you need to get the playerid of the "name" entered when calling the callback
