Magento Checkout stuck on billing info
After years of it working fine, our Magento website products.aei.eu has stopped functioning correctly. Currently it works well until a user tries to checkout. Upon clicking continue on the billing information the page doesn't respond and users cannot continue their purchase.
I have tried adding a blank <div class="col-right"></div> in onepage.phtml as suggested in another post with no success.
Any help on this would be greatly appreciated as it is urgent we fix this.
Thanks in advance
