TFS 0.X Gesior ACC [World_Id] Error

[Vizjus]

Today i came around to my otwebsite and found that creating accounts wouldnt work.
but it was just fine yesterday!
hmm
createaccounts.php always thrown me the error saying please select a gameworld
so i changed the if function of game world!
posting it here in case google search is gonna bring someone with similar problem 1 day

if(!isset($_POST['world']) || empty($_POST['world'])){
$_POST['world'] = 0;
}else
$e['world'] = 'Please select a game world for your character!';

or
if(!isset($_POST['world']) || empty($_POST['world'])){
$_POST['world'] = 0;
