There's a problem here. browsers do not send Referrer when on an https site. And they refuse to work without the header

For geeks: could not find "Referrer" header.

Point of interest, it's actually "Referer" - a misspelling that dates back to the original HTTP RFC 1945.

See http://en.wikipedia.org/wiki/HTTP_referer

Oops, good catch, thanks! Hadn't thought of this.

Apparently the problem is just sending a request https->http. https->https should work fine. Adding SSL asap.

EDIT: now you can also use https://api.formspree.com/[e-mail]

The rules are more complex. I'd say just do away with the refer(r)er. http://webmasters.stackexchange.com/questions/47405/how-can-...

Maybe later when you have a real problem, fix it then. Let's cross bridges when we come to the river, that way we'll all have much simpler code!
