Error when trying to complete purchase.
I'm testing this site on my server and I thought all I had left to do was add in the return/error/cancel URLs on the pp_advanced.php page and it would be good to go. An item goes into the shopping cart then moves to the checkout page and when I hit continue I get the following error:
Some required information is missing or incorrect. Please correct the fields below and try again.
Error: Field Format Error: Invalid URL. Please return to the website from where you started your purchase and try again.
Any ideas? I can provide access to the site URL or copies of any code/page as needed.
Thanks.
