I downloaded and installed the latest version of Jetpack not that long ago, and since then any posts I make are ignoring the subcatagory in the url when it posts on Facebook
I.e. http://radio.shelliescards.info/sched-shows/four-more-great-new-shows-coming-soon-very-soon/ was put on FB as http://radio.shelliescards.info/four-more-great-new-shows-coming-soon-very-soon/?fb_source=pubv1 which brings up a page not found error - as I would expect it to do.
If I just type sched-shows/ in the correct part, the post loads no problem. The other thing to add is that sched-shows is the default post catagory
This did not used to do this, and had been working perfectly until the latest update.
