Paypal integration problems

Several customers are reporting the Paypal integration is not working.

The bahvior is the following: after you fill all the form details and click submit, the button text changes to "Please wait..." and nothing happens.

The specific form is this one:

I also tried this on a different form and the problem is the same.

This should now be fixed.  Please let us know if the issue persists and we will take a look immediately.
