I am no longer able to edit a form and have the following error message

I am receiving the following error message - Unexpected error occurred control paypal and can no longer edit my form.

Could you please provide the form link so we can investigate it?

I am assuming that you're referring to this form: http://www.jotform.us/form/73516442305148

If yes, I checked the form and I can see the Payment field properly. Here's a screenshot:

If you're referring to a different form, please let us know so we can check it.

Thanks,
That's the form, but I since updated by going back to a previous version.
I got an error message after trying to edit the "my products". My screen
would then go completely white. Not sure what was going on. I cleared my
cache as recommended.

Please try clearing your browser cache. Here's a guide that you can follow: http://www.refreshyourcache.com/en/home/. Choose your internet browser and follow the guide.

I cloned your form using Incognito mode and I was not able to replicate the issue. Here's a screen capture of my test using Incognito mode:

Please try it and let us know how it goes.

Thanks. I did clear the cache and reverted back to an earlier addition so
you won't be able to replicate. Took some time to rebuild the form, but is
working fine now.
Thanks!!
