Hi I have problem in my onepage checkout. I can't choose pay method because ajax all time is reload. In console I have 500 (Internal Server Error) (in adress onepage/json/saveShippingMethod. I can't find this controller. In exception log I have 'Mage_Core_Exception' with message
'Mage registry key "themeMediaUrl" already exists' in /var/www/home/mmuzyka/byinsomniabiz/app/Mage.php:595. Do you have any hints?
edit: I have the same issue and I change code from this case but not work. Stripe don't work on IWD OPC
