Modern Problem with create character on Rookgard

[Kudzu]

I have set this line in config:

/*List of vocation available to choose when creating new character*/
$config['vocations'] = array(1=>"Sorcerer", 2=>"Druid", 3=>"Paladin", 4=>"Knight");

to


/*List of vocation available to choose when creating new character*/
$config['vocations'] = array(0=>"None");

but I still see all characters but I can't made character. Any help?
