I too ran into the 'processing ....' page hanging when viewing the cart. I can bypass it and place an order but then there's no place to enter coupon codes. That's done on the 'view cart page'.
Cleared my cookies, cleared my cache, still couldn't view the cart to enter the discount code. No biggie - order sent anyway.
Yea! Ikenvpae is back in town.
Congrats Isaac for getting going again, and a big thanks for all your work.
