I upgraded our blogs to MovableType 4.23. I was panicked for a second since it looked like I had crashed the blogs badly and couldn't either upgrade or backout to the originals. What had happened was a typical n00b mistake in UNIX, I had copied the files to the mt-static directory but had accidentally copied the folder itself, not the contents, so for a while I had a directory named:
with all the files in it and I couldn't figure out why it didn't work. Duh.
p.s. I wish MT did more sanity checking for idiots like me. :-)
