Movable Type problems on

For some reason Movable Type on my host ( has started flip-flopping in its behavior. So now I cannot post an entry directly. If I publish an entry it does not appear on the main page. I have to an explicit rebuild which looks ridiculous.
The category archiving has failed completely. Comments do not work. The worlds are colliding.
My hosting provider graciously declined to help which means I am on my own to debug.
So I have to explore other options like
(a) Fix the problem
(b) Move to another hosting service
Till one of them happens there will not be any more posts. If you have suggestions for a good MT Hosting Service please mail me at tiptronicus [at] gmail dot com.
