Well after a couple of false starts I think I’ve now got Movable Type version 3.3 (3.32 indeed) working. I had some false starts earlier which gave a “PreSave failed” error. Googling it really didn’t help, and I was flumoxed. But I think that I failed to update a folder since a second reinstall seems to have done the trick.
It’s too early to say yet how good the new version of MT is, but I’ll be having a closer look over the coming days.
