Hi, your contact form is broken because no session is started. I got the session error here: wpbackitup.com/contact/#FSContact2 Try to send yourself a message and you will see the error. I have some questions to ask about buying the Power version but not in your support area.
Hint: many hosting services are quietly migrating files to 'the cloud' and it breaks some scripts. Your host needs to fix the problem.
I'll stop back and try again
