Why does my PayPal integration keep disconnecting?

We've been running registration for a small training and I have had to fix the PayPal integration no less than 5 times because people complain that the form is not directing them to PayPal site when choosing that option.  We're about to open registration for our conference, usually about 250 people. If I can't get this fixed permanently this week, we will be cancelling our subscription and switching back to another service that is more reliable. 

I was looking into your form id 42165379189971 and saw that your payment option was check/wire transfer? Did you modify the form and replaced it with check/wire transfer payment method?

I was testing the integration on my end so far the integration doesn't get disconnected.

No. I have not changed it since the last time it worked properly. 

There are two options. Check - which conditionally shows our address and instructions. And credit card, which should conditionally redirect to PayPal.  

It worked for several days and then suddenly stopped working again. 

This not a common issue, since our forms are really stable, and nothing is supposed to be changed on its own.

There is a Revision history tool available for forms. Can you try to use it to restore the form to a Sep 1st state, for example?

Then get back to us, so we will be able to check if your form is configured right.

We are looking forward to hearing back from you.
