For some annoying reason my Page.php stopped working properly, im unsure why its doing this but i am unable to add tabs to the basic pages and all that follow. Its just not working..

It sucks since my deadline is tommorow and right now it decides to go buggy..i dunno what went wrong, could be that its extended in homepage but i doubt it.

Heres the code:

public static $db = array(
      
      'ColumnRight' => 'HTMLText',
   );

   public static $has_one = array(
   );

}

function getCMSFields() {
$fields = parent::getCMSFields();

      $fields->addFieldToTab("Root.Content.Main", new HTMLEditorField('ColumnRight','Column rechts inhoud'));
return $fields;
}
