I contacted WordPress support yesterday to find out what was going on with the pingbacks. All the Happiness Engineer was able to tell me is that it’s just me. Everyone else’s are working. Mine are, in fact, not working in either direction – I pinged back to Dale’s site yesterday for the photo challenge and he never received my link.
So it seems WordPress doesn’t like me; your guess is as good as mine as to why. At the moment I’m still waiting for a developer to get back to me. I’m not holding my breath that it will happen before 2am when I post my next prompt, so if you plan to participate in One-Liner Wednesday tomorrow, I’m afraid you’ll have to manually enter your link in my comment section, so I and everyone else will see your post.
Apologies for the inconvenience. Hopefully this will get sorted out before Saturday and SoCS rolls around again.
