Contact Form not working

Hi! I have been searching for an answer to this for days and I don't see any posts with my specific problem (or I'm not looking in the right place)

My Contact Us form does not work. When a customer clicks send it just refreshes the same page. I don't know enough to use the debug tools that everyone mentions to ascertain if it a zen issue or my host settings. Please help!

website is http://www.graphxfairy.com

namecheap is my host

Apache version 2.2.15
PHP version 5.2.13

My email settings:
E-Mail Transport Method sendmail
E-Mail Linefeeds LF
Use MIME HTML When Sending Emails false
Send E-Mails true Info
Email Archiving Active? false
E-Mail Friendly-Errors false
Email Address (Displayed to Contact you) [email protected]
Email Address (sent FROM) [email protected]
Emails must send from known domain? No
Email Admin Format? HTML

Does anyone have any ideas?

Start by replacing the default/custom template file in your template directory called tpl_contact_us_default.php with a fresh correct file from Zen Cart for your version.

Thank you so much for taking the time to respond. It did not work.

Checkout forms work?

It seems so except I offer digital downloads and a few people have said they are not getting their link, but it looks as if they did on my end.

I am seeing this at the top of all of php files. I know I was hacked and went through the steps to recover, but it keeps coming back. Would that be the problem?
