Hi - please prioritize. My site is inoperable after upgrading.
When I reach the registration page during the subscription process, I get a white screen of death. It DOES create the WP user account. I can reload the page to then get the Subscribe button and proceed.
Thought it could have been a cache plugin (W3) - disabled it, did not help. Defaulting to Twenty Twelve theme (from Thesis) does not work.
Also, Coupons are not working. I created a coupon, got the message "Coupon added", but nothing shows up on the coupon admin screen. When I attempt to use the coupon, I get this message: "The Coupon code is invalid."
