I updated to WordPress 1.5.1, and it seemed to work fine. Later, when the hours showed it was the next day, I read that the RSS feed wasn’t quite what it should be, even if it might seem so to begin with. There were also a bugfix.
Well – I want my RSS feed to work, of course, so I installed the bugfix. And when I finished my first plugin (abbreplace) I proudly wrote an entry about that. Which – unlike what I wrote before the bugfix – never showed up in the RSS feed.
I changed back to the original, unpatched file. Hopefully, all is well now with this entry and the feed.
