Everything does look correctly setup as far as the object/action go.. the only thing I see wrong is that your site seems to be trying to use SSL for some stuff. If you open the HTML on your page, you'll see https is being used for a few of your links. It's also not just within JFBConnect, JomSocial seems to be adding their links thinking that the current page is being loaded over https.
One of the Open Graph tags, in particular though, is probably the problem:
<meta property="og:url" content="https://www.inthemix.me/archive/dubai-legends/danz-kay-tek.html"/>
That's saying that the 'real' link for the current page is the https version. However, you don't seem to have a valid SSL certifcate. The Facebook Debugger can ignore things like SSL certificates. Their real parser for actions won't though, so it's probably not reading your object page at all... and then throwing the error you see.
Do you know why your site is using a mix of http and https for URLs? That's gonna need to be figured out first and I think it may help you with other issues, since JomSocial's AJAX plugin is being loaded over https, which means that anyone that hasn't explicitly approved your SSL cert by going through the warning won't be loading that file.. and a lot of JomSocial's functionality won't work without AJAX.
Hope that helps. Would love to hear that the video action is working for you, so let us know if you get it going. Excited to hear about any actions that users are submitting.
Thanks,
