Since Luis released ContentBox V1.5 I think was the version that introduced this bug, the problem is that when retrieving content from a cache.ContentBox sends back an HTTP status code of 203. The problem is that Google doesn't like this at all, especially when posting links onto Google+, because as the description of that code indicates, Google+ considers the content as not the Author who is posting it.
This was raised with Luis and the team at ContentBox, but so far after 3 months it still hasn't been fixed.
So how do we fix it then.
