The "Create a new account" page of the support ticket site is broken.  Firefox, Chrome, and IE all show something like:

CAPTCHA Verification

Please enter the text you see in the image into the textbox below (we use this to prevent automated submissions).

... with no CAPTCHA available to complete.  I tried Private / Incognito windows to rule out cookie conflicts, ad blocker turned off, no preprocessing of the web page at all.  I mean I guess it's doing a good job at preventing automated submissions, but it's preventing my interactive submission as well.

Chrome's console logger shows an error: "X-Frame-Options may only be set via an HTTP header sent along with a document.  It may not be set inside <meta>."  Then a later warning: "Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened." with a source of hxxps://www.google.com/recaptcha/api/challenge?enormous=query&string=here .  Looks like you're running into some cross-domain scripting restrictions with your CAPTCHA service.
