Goal: Only experts, moderators and admins shall be able to close questions
My attempt in qa-theme.php without checking the privileg, just trying to remove the close button:
// abstract method: first and safest place to change content and layers
// QUESTION page
// $this->content['q_view']['raw']['closeable'] = false;
The effect: closable is set to false, but the close button still appears.
Guess I need to override the button output funtion and to the check there?
