Submit button not working properly

When users try to submit my form, the submit button stays stuck at "please wait". However I do receive (repeated) submissions every time they press the button, but the user gets an error page.

I have tested your form and seems like this has been disabled, so I cloned it and performed a test, the form seems to have worked, here is an example about the result on my end:

I cleared your forms cache, kindly perform a new test and let us know if the problem persists.

I just enabled the form. This is what I get after I submit the form

Thanks for the screenshot.

I have just checked your form again and it seems disabled, may we enable it to perform a test and then disable the form?

Also, I would recommend you to kindly try using a different internet connection, browser or device, it's possible that an app installed on the device/browser or security restrictions in the network are causing this issue.

Let us know how it goes.

Yes, please enable it. We have tried with different devices. It was working fine last week

I tried to enable and test your form. I was working as expected. Can I gently ask you to enable your form in the Form Settings section under the Settings tab?

Please give it a try and let us know how it goes. We will wait for your response.
