 * After installing the quiz I had problem after each operation to save or update
   a post:
    something like: “Warning: Cannot modify header information – headers
   already sent by …” so I edited the SS quiz php page and add at the beginning 
   of the script (above everything) <? ob_start(); ?> and at the end: <? ob_flush();?
   > now it works. hope it will help.
