Error establishing a database connection

Same Problem.

The testconnection.php script for testing database connection connects successfully but still WP shows Error establishing a database connection.

Please Help.

Hello – I am receiving the same error – Error establishing a database connection – my blog is:

http://gulfscapes.com/2011-Mardi-Gras-Gulf-Coast/

I’ve gone through 8 hours of reading threads about correcting a partial upgrade, manually installing a blog, checking wp-config.php, learned how to deactivate plugins when I can’t log in … I’ve tried everything I can find.

I deactivated the theme manually as well – at least my page is up but if you click on anything it says – Error establishing a database connection

I can’t get to login.

I am using yahoo hosting …

Not sure what you mean?
