Problem with contact formular

can you help me? I use the Script and after the Upload there is only that and no contact formular. What made i wrong?

How did you build the contact form did you write it yourself in an HTML page or did you use stacks or a plugin

thank you. I have upgrade to PHP 5.6 an now it is ok.

But when I send a contact request there is another mistake:
I’m sorry, there seems to have been an error trying to send your email. Please try again.

Can you help me?
