Sorry for anyone who was getting “page not found” returns on some of the items on the front page of the blog. I’d installed a new plug-in that was a bigtover-earnest in rewriting URLs.
One of the great things about WordPress is the sheer volume of plug-ins created to provide all sorts of functionality and features. Sometimes they choke, and my fault for not re-checking what was happening after I installed this one.
All’s well and back to normal.
