Technical Notice
Last night I upgraded my WordPress software to the recent version 2.5.1. It was a substantial change since I had been at version 1.5.2 for some time. Today I tidied up some details, particularly in the plugins.
The upgrade seems to have gone smoothly and it looks like I have everything working again now.
Please, if you happen to notice something that has gone awry and not been repaired, let me know in the comments.
