redirect invalid forum and invalid thread to home page or index?

[marcus123]

@DrXotick thanks very much man.

@Leefish great idea thanks a lot. I will replace all :

error($lang->error_invalidthread);
error($lang->error_invalidforum);
error($lang->error_invalidpost);

With:

if (in_array($mybb->user['usergroup'], array('3','4','6'))) {
error($lang->error_invalidthread);
}
else
{
redirect("index.php", some error goes here);
}

Just nailed it thanks




P.S. Do you think I can create a plugin for this without modifying core files?
