Table prefix (if you want to run more than one WordPress in a single database)
If for any reason this automatic file creation doesn't work, don't worry. All this does is fill in the database information to a configuration file. You may also simply open wp-config-sample.php in a text editor, fill in your information, and save it as wp-config.php.

Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the %1$s database.

Are you sure it exists?

Does the user %2$s have permission to use the %1$s database?

On some systems the name of your database is prefixed with your username, so it would be like username_%1$s. Could that be the problem?

If you don\'t know how to setup a database you should contact your host. If all else fails you may find help at the WordPress Support Forums.

Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the %1$s database.

Are you sure it exists?

Does the user %2$s have permission to use the %1$s database?

On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?

If you don\'t know how to setup a database you should contact your host. If all else fails you may find help at the WordPress Support Forums.
