Loading ...I have to go thru that check every single time I log in… because I come thru a different country on the TOR network every time, and I don’t let my browser store cookies long term. It’s pretty embarassing when I goof, and a red line appears at the top that says:
YOUR MATH SUCKS! TRY AGAIN.
That ‘cookie’ that was stored in your browser to identify you probably got flushed, somehow. Glitches happen.
