Yesterday I upgraded WordPress (the publishing system for the blog) to version 4.0. Then I tried to access the comments and got an alarm saying the comment database needed to be upgraded, with no alternative but to click OK. I did, and Disqus (the commenting system) went sideways.
With a little bit of angst and a lot of frustration, I got it to work first thing this morning. We seem to have lost one comment on the Pooh and Piglet image post from John_from_Aus, but since that was asking about the commenting system, I think we can get along without it.
