Installation Step 6 — Error establishing db connection

6. Run the WordPress installation script by accessing wp-admin/install.php in your favorite web browser.

A: MySQL database properly set up and functioning (no tables of course, but I figure that’s what the installer will do)

B: Files and directories unzipped OK

C: FTP to root directory looks OK.

D: Double checked db name and user name and password. At my hosting site, I notice that “MySQL running on localhost as myusername@localhost, so I figure local host is correct. Not sure where to look next.

Would appreciate a suggestion or two
