It's just keep loading and doesn't do anything. This bug isn't new, but i've waited a bit before opening a thread for it. It has started doing this about a week ago and since then i can't check my previous shop transactions. Please fix it, because usually the pop-up notifications doesn't show the sold items correctly.

Thanks in advance!

EDIT:
Some additional info.
It doesn't work in IE 11 and in Chrome.
In Chrome's console i get the following error codes:
Failed to load resource: the server responded with a status of 500 (INTERNAL SERVER ERROR) http://dispenser.tf/tasks/?addr="my_shop_address_what_i_don't_want_to_share_with_everyone"&task_type=&completed=1&reverse=1&entries=10&page=1&_=1415441206776
