Web Host Change, Now PHP doesn't work

[Sothpaw]

our web hosting company fell off the face of the planet 2 days ago so we moved to another one.
now our "Contact Us" page doesn't work. i've utilized PHP so a browser can fill out the forms and hit the send button. it worked fine before but not now.
the hosting company says that they are running PHP 4.4.7 and have PHP4+ and PHP5
but i don't really know what that means for me. i don't have any script line that defines what PHP version to use and i never have.
any help here would be great.
if you need me to post my PHP code i will but you could go see it here.

thanks for any and all help in advance

Please check your error logs to see if something is going wrong. It is likely that your smtp server isn't configured correctly, or something. Check for errors first and then get back to us.

sorry but i don't know what you mean.
is there a web recourse that can explain this SMTP error log to me?

You have to check your PHP error log which defaults to your web servers error log or wherever the error log directive points.

Its more than probably a register globals issue if its a contact form. Your previous server probably had register globals ON, where as your new host has them off. Thats what I`m assuming anyway.
