Upgrade In Process
I’m currently upgrading to Movable Type 4.01, so things may become a little strange.
Good news – I think I figured out what the problem with using TypeKey and comments is.
Bad news – it still breaks, but you get a lot further before it breaks! [UPDATE: It’s Fixed]
The publisher’s side of MT 4.0 looks really slick. I treated my site as a new install, only saving the templates, entries, and comments from the previous version. At some point I need to update my templates to take advantage of all the new features.
