Why am I getting a "go back and fix" issue when submitting my form?

I'm experiencing the same issue when embedding the form into my own site. 

If I try the standalone form, the back link works just fine. It's when the form is embedded that this is an issue.

Also, any idea why the Square sandbox test credit cards would always return a card error?

Thanks

Based on your explanation, the issue seems to happen only when you have embedded your form, may you please share us the link to the webpage so we can further investigate it? 

Regarding the testing credit card numbers, which error are you receiving? 

I would recommend you to check that your integration has the test mode turned on: 

Please also share us the form you're working on so we can test on it. 

Looking forward to your response. 

This is the page https://www.mypachis.com/birthdays-and-private-events/booking

The credit card integration is live, so using any invalid credit card number will give you the same blank page result.

Thanks for the help

I tested your form with test card, and since it is a live payment integration, I got this error:

Which is correct.

I don't have a way to test with the live card I'm afraid.

If you can replicate this error, please share us the console report when the issue occurs so we can get a better picture of the problem, here is how to do that: https://www.jotform.com/help/453-How-to-get-a-console-report-from-most-common-browsers

We'll wait for your response.

Thank you!

That error works as expected. The issue is when clicking the Go back and fix link, it just takes you "back" to blank screen. Or the area where the form is usually loaded is blank, nothing gets loaded. 

The user needs to refresh the page, losing all of the information they typed in previously.

Ok, if the form is redirecting back to an empty section where the form should be then there is an error since at least the form should be displayed there. 

Now, may we get a screenshot about the error, please do not attach the image on an email reply to this, instead kindly follow this guide: https://www.jotform.com/help/438-How-to-Post-Screenshots-to-Our-Support-Forum 

I also checked your page and it seems like you embedded your form using the JavaScript code, please try using the iFrame code instead and see if that makes any difference: https://www.jotform.com/help/148-Getting-the-Form-iFrame-Code 

Let us know how  it goes. 

There is no error whatsoever when clicking the Go back and fix link, just a white page.

I'll try embedding as an iframe and see if that changes anything.
