Visitor Message Default Profile Tab Issue

[Xen Chaotik]

Okay, so I have used a couple of different methods with this in the Plugin Manager. Both codes work on most profiles, but there always seem to be some members that experience their profile tabs being Mentions, Quotes, and others for example when I have these plugins active.

First plugin code is

if (!$vbulletin->GPC_exists['tab'])
{
    $vbulletin->GPC['tab'] = 'visitor_messaging';
}

hook - member_build_block_start

and

if (!$selected_tab)
{
    $selected_tab = 'visitor_messaging';
}

hook - member_complete

I have tried both at the same time and one at a time, but there always seems to be an issue of it not working on all profiles. Any help is much appreciated.
