So, I installed Movable Type 4.1 the other day to play around with it. Unfortunately, it must share some key files with MT 3.34, because despite installing it in a different directory, it has borked up my MT3.34 installation. All the HTML files are still there, but I can't add new entries or access the export functions, nor can I edit templates other than the index. So I'm backing up the HTML and SQL databases and attempting to re-install 3.34 over 4.1 and hope it works. If it doesn't, well...I can still access my old MT 2.63 install, it looks like, and export from there. That goes up to March of last year, so it's not too bad.
