When I go to the Flag Counter Management section to update my credit card it won't work. I've tried three different cards, click update, it will refresh, clear all the fields, and not update. It won't even display a message why it won't update. I've tried AMEX, Visa, and MC nothing works, they are all valid cards with tons of room on all.
