The order form on our site stopped functioning after I updated the theme and my plugins. I think the form is generated by Cornerstone somehow, because the form remains even after all the plugins are deactivated and I can see the form fields when in Cornerstone edit mode, instead of shortcodes.
I turned off all of the plugins and the form still doesn’t work. Click on Submit button and nothing happens.
With all the plugins turned on, the button is press-able and the page loads (indicating something happening) but instead of a confirmation, it just returns a white page. The person on the other end never receives a form submission.
I can’t test the theme because if I switch to default theme the form goes away.
This is an urgent problem.
