Using JetPack v2.3.5
Since yesterday, I think, links produced by Publicize and pushed to my facebook page are malformed. Essentially, they seem to be missing out categories (which are part of the permalink path structure) and include a facebook suffix.
I think the suffix is usually there, anyway, but is normally hidden.
As an example, if I were to post an article with the URL:
http://www.moshville.co.uk/news/2013/08/test-4/
...then the related facebook post has a link such as:
http://www.moshville.co.uk/2013/08/test-4/?fb_source=pubv1
I have removed and re-added my facebook account from the Publicize settings (as detailed elsewhere), which did not help. I also checked and clicked "Save Settings" in my General and Permalink settings in WordPress, just in case they needed a "nudge".
At least I have spotted that I'm not alone with this problem, and that it affects Twitter as well (though I don't use that function so wouldn't have spotted it myself), so at least I know it's not an issue with facebook itself.
Thanks for any help!
