How can I edit payment widget?

I recently realized our coupon codes all say "affects no products." Every time I attempt to edit the settings on the coupon codes, the screen goes white and does not indicate it is trying to load anything. If I eventually refresh the page, it goes back to Form Build and I continue to encounter the same problem.

I have tried this multiple times, in different places - I appear to have a strong internet signal and everything else works, but editing that payment form seems impossible.

What can I try?

Thank you!

There are errors in the background that are causing the problem;

Adding a new coupon codes works, so you may consider doing it this way. You can delete the coupon codes with no product selected. If this isn't an option for you, or if this is happening in multiple forms, let us know and we'll be glad to create a report about it.
