Cannot log in to, 403 error

Sorry to post this here, but I’m getting a 403 error when I try to use the Contact link on too.

Every time I try to log in or reset my password, I get this error:

Forbidden (403)
CSRF verification failed. Request aborted.

You are seeing this message because this HTTPS site requires a
’Referer header’ to be sent by your Web browser, but none was sent. This
header is required for security reasons, to ensure that your browser is
not being hijacked by third parties.

If you have configured your browser to disable ‘Referer’ headers,
please re-enable them, at least for this site, or for HTTPS connections,
or for ‘same-origin’ requests.

More information is available with DEBUG=True.

I’ve never had this error before on any site, and I am pretty sure I was able to log in to the last time I tried, maybe a month ago. I am using Firefox 40.0.3, have disabled tracking protection for and turned off Ghostery and AdBlock.

Any help would be appreciated.

Using my googlefu I’ve determined it might be corrupted cookies. You can clear firefox cache and then remove the cookies from the site and try again.
