The first time I installed it with 3.4.1, it worked;
the second time, after delete my WP website database(to clean up my db), and reinstall WP with a new package downloaded from wordpress.org, the latest 3.4.1, it did NOT work.
The error messages are pasted below.
Probably reason of this is that you did not create configuration file. You might want to use setup script to create one.
---> this "setup script" lead to my website in a iframe, did not solve anything.
MySQL said: #1045 - Access denied for user 'root'@'localhost' (using password: NO)
---> I have no idea what it said, I can access the other phpmyadmin in my website host's control panel.
