Well, it’s happening again. Even the debugger doesn’t work.
I get this message:
Errors That Must Be Fixed
More Than One OG URL Specified: Object at URL ‘http://domain.com/2013/03/accident/’ of type ‘article’ is invalid because it specifies multiple ‘og:url’ values: http://domain.com/2013/03/accident/, http://domain.com/2013/03/accident/.
Thanks dwasko, the open graph meta tags seem to work, the first image facebook fetches is the first one published, not the ones from the grid.
I don’t have to use the debugger (yet).
