In your snippet call, you have:
&tpl=`ContactForm` &report=`ContactFormReport`
That means the snippet is looking for a chunk called ’ContactForm’ for your form layout and, for the email template, it’s looking for a chunk called ’ContactFormReport’. If you don’t have these chunks available in your site install, then you will get the error.
Check in MODx Manager -> Manage Resources -> Chunks tab. Do you have any chunks with the above names? If not, that’s your problem. If your other site is working fine with eForm, copy the chunks over from that site
