Did anyone resolve this yet. I have updated versions of Contact Form 7 (version 3.1) and WordPress (version 3.3.1.) and am using the latest version of Suffusion. Forms work fine unless I to use file upload code in forms. Then the submit button just results in spinning arrow even if nothing is placed in form at all. If I do fill in the form the email is sent but no confirmation message and the arrow continues to spin until you refresh the page.
I would love to know the remedy. I have looked all over the web for a remedy hoping for a relatively easy fix (as I am merely a novice user).
