I finally took the plunge and upgraded my Movable Type blog hosted on Yahoo! Small Business (Merchant Solutions, actually). I found some invaluable resources if you are trying to get Movable Type 4 working on your Yahoo! hosting account.
I felt like I needed to do this for a couple of reasons. Finding any support for MT 3.x was getting harder and harder. Also, my Yahoo! hosted MT 3.x had this weird behavior with the archive links. Even after setting the archive links to point to my domain at http://www.topright.com/blog, it always returned to showing a path of http://p7.hostingprod.com/@topright.com/blog/. I fiddled with the settings on the installed version of MT. I hired a consultant to "fix" it. He was unsuccessful despite claiming he had done it before. So, being the determined person I am, I figured I'd try to upgrade to MT4 or find a new blog host (at an additional monthly cost which made me unhappy).
So, the two resources which I found invaluable are below. The first is from Chad Everett of Learning Movable Type. He has an article called Install Movable Type 4 in Yahoo! Small Business. If you can follow those instructions and get it to work straight away, then you are golden.
I had a problem where I kept getting an error message saying: Can't find included template module 'HTML Head'. There is a post on the MT forum that is perfect. Actually a guy by the name of Micah provides the answer at the bottom. Here is that link.
Now I don't have any excuses for not posting any more. I can take advantage of all the cool features in Movable Type 4 for FREE because it's open source and I figured out how to make it work on Yahoo! Small Business hosting. Cool.
