You shouldn't need to create Open Graph objects for every page. JFBConnect will automatically set the og:type to 'article', which is generally the best fallback type for all content on a site if no object has been defined for that page.
The only exception to that is that we will set your home page to a type of 'website' (unless you've created an object or an override for that page). The error above seems to indicate that the type is set to og:type="website", which makes me think it's your home page. The error is that the og:title property isn't set for some reason. JFBConnect, again, should be able to generate some title for your page using either the article title (if it's an article) or even the standard meta title for the page. If none of that exists, it's possible that JFBConnect isn't setting the og:title tag, in which case, you'd get that error. One thing you can try is adding the following to the page with the error:
{SCOpenGraph title=My title for this page}
That will force the title and may remove the error.
If that doesn't help, can you post, or Private Message, a specific URL where you're seeing that problem? I can't really diagnose much without seeing the actual HTML output on the page.
Thanks,
