I know there are multiple topics concerning this subject but I can't get my error fixed. I was on magento 1.8, everything was working great but suddenly I got the problem that in the checkout module, I can't continue to Shipping Information. Continue just doesn't do anything. Unless (and now the fun part starts) I use Ship to Different adress (bottom option). Then it DOES continue. I have upgraded to 1.9 but same problem. I can't find any errors (not in the log, in magento or apache and not in the JS, f12 in chrome), it works using the default template but my template only has the files in the checkout folder:
success.phtml cart.phtml onepage/login.phtml multishipping/success.phtml multishipping/shipping.phtml multishipping/overview.phtml multishipping/billing.phtml
cart/some irrelevent files i guess
My template realy doesn't do that much i recon!
I know this isn't a really high quality post but is there anyone who can point me in the right direction?
