another can’t select database install problem

Sorry to not be original, but I’m getting this on install:

We were able to connect to the database server (which means your username and password is okay) but not able to select the tgd_combo database.

my config is:

// ** MySQL settings ** //
define(‘DB_NAME’, ‘tgd_combo’); // The name of the database
define(‘DB_USER’, ‘modder’); // Your MySQL username
define(‘DB_PASSWORD’, ‘xxxxxxx’); // …and password
define(‘DB_HOST’, ‘127.0.0.1’); // or 127.0.0.1 99% chance you won’t need to

i have:

• tried multiple databases

read lots and lots of posts on this subject

• looked at the database in myphp
• tried “localhost” and the literal address shown
• replaced the db user PW

FWIW:

• the db is a clean new one
• I’ve successfully installed WP on this server before
• the host company has just moved up to msql 5 db’s
• am designer not php dood, but reasonably install savvey

i really have spent a helluva a lot of time on this – would very much appreciate some advice..

TIA
