Still having the same problem. The order details get inserted to the database, but the order summary does not.
The customer just see the error Page cannot be displayed after they click the order submit button.
I cannot recreate the error myself - it works for me. But there is an issue because it has happened more than 10 times in the past 90 days.
I have moved the site to a new server, that did not work.
I have reviewed the checkout process - this is a manual setup where the credit card info is submitted to the database and the client runs the CC manually.
I am attaching the pages that make up the checkout process. Is there anything that you can see in these pages that would be an issue??
Not sure what to do.
