Please, post a pastebin link.
I'll check it.
EDIT:
Use switch instead of else if like:

PHP Code:

stock ErrorMessages(playerid, errorID)
{
    if(errorID == 1) 
    if(errorID == 2)  return SendClientMessage(playerid,RED,"ERROR: Player is not connected");
    if(errorID == 3)  
    if(errorID == 4)  
    if(errorID == 5) 
    return 1;
} 


to

PHP Code:

ErrorMessages(playerid, errorID)
{
    switch(errorID)
    {
        case 1 : return SendClientMessage(playerid,RED,"ERROR: You are not a VIP");
        case 2 : return SendClientMessage(playerid,RED,"ERROR: Player is not connected");
        case 3 : return SendClientMessage(playerid,RED,"ERROR: You need to be VIP level 2 or above to use this command");
        case 4 : return SendClientMessage(playerid,RED,"ERROR: You need to be VIP level 3 or above to use this command");
        case 5 : return SendClientMessage(playerid,RED,"ERROR: You need to be VIP level 4 to use this command");
    }
    return 1;
} 


By the way, you don't need stock as a filterscript.
There is too many useless callback called there.
