Hi Scott,

I didn't see it as a hack.

I think the only clarification to the instructions: https://docs.zen-cart.com//user/payment/square_errors/
would be a step 5: Save

Everything after that is only necessary if you get the blank screen. Perhaps that portion of the remaining instructions should be boxed or indented or ?. Though I didn't have a problem understanding the instructions, others might.

Your post helped me get to an understanding of the process. - Thanks!
