Hello,
When i try to redeem my Items of this weeks event i get an Data Base Error with this message:

warning: array_pop() expects parameter 1 to be array, null given in /virtual/home/www/vhosts/games_20121213_1401/includes/webmall_utils.inc on line 297.

nevermind, it seems just to not working wth firefox but with google chrome. Sorry for double post. The threat can be closed ;P

I believe the javascript was disabled or blocked on your Firefox browser.
