One-Page Checkout [Support Thread]

Hello Cindy - I hope this finds you well.

My customers are encountering this message when trying to checkout using the checkout tab in the cart - tab takes customer to /index.php?main_page=login and then the message appears after clicking 'Guest Checkout';
"Sorry, but our expedited checkout process cannot be used. Click here to use our alternate checkout process."

I also have the yellow 'checkout with PayPal' tab in the cart which works fine, i.e. the transaction completes as it should.

I searched this support forum and found a couple of references to this issue (https://www.zen-cart.com/showthread....ss#post1357324 and https://www.zen-cart.com/showthread....84#post1362684) to this issue however I'm not sure that my circumstances are the same and I didn't see any resolution to the issue in those threads.

I have PM'd you some debug logs which hopefully can help you to help me find the source of the issue (I didn't want to post them in here for security reasons).

many thanks,
Mike
