Things are going to look funny for a while. I upgraded to MT 3.33 (a security-critical update), and there has been a significant change in the template layout structure from my previous version (3.14). Expect it to be a few days before all the content is back in its usual places.
An installation note: When I uploaded the files to my server, I forgot to move the new static files to the old static file directory location, outside of the cgi-bin directory. I also needed to change the StaticWebPath variable from a relative path to a full URL. Without doing that, the new automated upgrade process doesn't work (it appears to stall after telling you the process has begun), nor does the new Style Catcher. Since I have customized the names of my comments, trackbacks, and search scripts, I needed to change those file names to match those in my config file.
