After backing up my database, updating from 4.1.12 to 5.0.16 of MySQL, restore databases, and fix the privilege tables, everything works fine except that I cannot publish new posts. The page says that the post got saved but when I go to the blog page it is not there. Using WordPress 1.5.2 with PHP 5.1.1 and Apache 2.0.55. Please Feel free to ask for any more info that might help troubleshooting this. Thanks.
