It has worked about 2 or 3 times out of the past 12 days. Have verified that cURL is working on my server. Also have a stack of error notices accumulating on my dashboard screen that I can't get rid of.
I can't explain how it actually worked those times, yet I saw the links on my FB.
Just reinstalled and nothing has changed except that today's post, after reposting after reinstalling actually made an entry on FB and the error previously listed for today went away. Tried reposting the others that had errors but I didn't have anymore success.
