open graph & og:type

Alberto,
First off, I'm very sorry for the delayed response to this post.

I'm glad to hear you got the read action all setup. We're working on more documentation and videos for other types of actions as well and will have them up over the course of the summer, as well as more tools for implementing Open Graph Actions.

From your pictures, everything does look to be setup properly. The problem looks to be that Facebook simply can't see your album pages as they restricted to registered users only. Facebook has a 'crawler' that will look at all of your pages, and on your site, those pages are redirecting to the login page:
www.fotozoom.it/component/users/?view=login
That page does have an og:type set as 'article', which is why you're seeing the error message you see.

Unfortunately, the only suggestion I'd have right now is to make your albums public. That will allow Facebook to properly 'see' the Open Graph tags set for those pages.

We are investigating a solution for later this year which will present the Open Graph tags to Facebook when they try to see a registered page, but I don't have a firm timeline on when that will be available as it's a big undertaking with a lot of technical hurdles in the way.

I hope that helps explain the problem, even if it's not what you're looking to hear. It should be easy to test your configuration, at least, by making the album's public and re-trying the action/upload. If that works, it will confirm that it's a privacy issue.

Thanks,
Alex

Facebook caches data about the pages it sees. After you make things public, you'll need to wait a little bit for their cache to clear and 'see' the changes.

You can use the Facebook URL Debug Tool to scan your album, or other pages, and see what Facebook sees. That also updates Facebook's cache, which may help fix things as well.

If that doesn't work, sure, message me any information about the site you can and we can investigate further. You can PM me by clicking the mail icon under my picture to the left.

Thanks,
Alex

Those are set directly by JFBConnect. There is no communication with Facebook to get those values. It's all set using information from the current page or from settings you've configured in JFBConnect.

I'm not sure where website would be coming from. That should only be used on your home page. As for the uploader page in general, that isn't what is being shared. It's the destination album. What is the Open Graph tag on the actual album page?
