Whenever I click on submit in a practice problem, a box pops up saying complete your registration and asks for my city, state and country. The problem is, while I can enter text in the city field, I can’t do so in the state and country field, as it won’t let me enter anything. I tried going to my account page and entering information, but the same problem occurs there. I have been a member for a year and have submitted many solutions in the practice section, and this has never happened before today.
