I have a Oscommerce website and am having trouble with the checkout. When customers login and try to continue to the payment page, it stays at the 'delivery information' page and does not move to the page of 'payment information'.
This problem does not happen all the time, but it does happen a few times each day.
I will pay $15 after the problem is corrected.
If you want to see the website, PM me and I will provide you with the link.
