Paypal Redirect not Working

Hi,

The plugin was working correctly, but now all of a sudden when someone tries to register for an appointment the process freezes when it goes to redirect to Paypal to complete payment. It leaves the appointment page and then just stops on a plain white page with no content.

With the console feature of Chrome activated I see there is this warning on the appointment page: “Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check http://xhr.spec.whatwg.org/”. Not sure if that is relevant or not.

I updated WordPress and your plugin to the latest version and still experience the same problem. I also disabled all other plugins, but that made no difference so it would seem there is no conflict with other software running on the site.

Please let me know what I can do to resolve this issue.

Thanks so much.
Lance
