Hello dear readers. By now you may have noticed the layout of the blog is back to normal. It will be recalled that a couple of days ago I had migrated this blog from a shared server to a dedicated server. As it turns out, one of the consequences of the migration was that the server defaults to a newer version of PHP. To get my regular WordPress theme functioning again, what I had to do is force it that this blog is running on a slightly older version of PHP. And indeed the theme functions again.
So now things are back to normal.
