This is the page I received once I tried clicking and buying a membership.

This also popped up while trying to buy coins. I would just like to purchase a month membership, can you please help me, thank you.

Looks like it's a problem with the paypal merchant. We'll have to tell Brock about that one, especially since we've gotten like 4 other reports about that this week.

I notified him

The problem comes from the 2-step authorization. You've got to disable your text thing temporarily, that's what I did.
