Hi

I am fairly new to this and am not sure if this is the right place, please re-direct me if it is not

I am just finishing up my cart and am testing the credit card processing. The system works properly including seeing the transaction approve and getting the order confirmation emails.

My problem is that instead of getting the proper "checkout_success" notification, I get a white page with an error that says "Warning: an error occurred, please refresh the page and try again"

If I refresh the page, it resends the information to be authorized and declines the second time because of a duplicate transaction.

I can't figure out why the proper checkout_success page is not being shown

any help would be greatly appreciated
