Just Tested Again Purchasing Different Item
I just purchased a different item and the process and returned email, etc. were all the same.
I haven't a clue why this is happening as I have not made any changes to any of the php files other than the ones I have made per my other posts at your instructions.
The two coding changes that I made because of the SSL certificate so the cancel and return would go back to the website and the success (both work)
Hopefully by looking at the jpegs of the process and the settings for store email and additional details on the product, you will know how to resolve this issue.
