So I tried upgrading my webserver to use MySQL 5.0.15 (As I had other things I wanted to work on that needed it), and got WordPress reading the database without much trouble. However, I'm not discovering that I can't use wordpress to write any new data to the database. New posts aren't registering, new comments, nothing. And it's not coming back with errors at me, wordpress seems to think that everything is working great. Anyone got some suggestions on where to start fixing this?
