Support » Fixing WordPress » Database error

  • I’m moving a WP installation from a development server to a soon-to-be-live server. I’ve moved the installation, but am getting the basic “
    Error establishing a database connection” error. However, a simple php script in the same directory as wp-config.php, with exactly the same details for the connection, can connect fine and query the selected DB no problem. I’m really confused by this!

    Any pointers to what I should be checking?

    Often, it’s invisible characters that mess things up.

    Use this script to get a finer-grained error message:

    As there are only 4 parameters, you can also manually retype them in wp-config.php

    Also, try reviewing the following codex for possible reasons and solutions:

    Thanks both. @sterndata, I’ve run that and it connects fine all tables are ok…

    Will work my way through the codex again…:(

    A ltitle update on this. If I intentionally use incorrect mySQL user details in my wp-config.php, I get the following (nicely formatted!) message:

    Warning: mysql_connect(): Access denied for user ‘root’@’localhost’ (using password: YES) in /var/www/pssru/public_html/wordpress/wp-includes/wp-db.php on line 1482

    Error establishing a database connection

    This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down.

    Are you sure you have the correct username and password?
    Are you sure that you have typed the correct hostname?
    Are you sure that the database server is running?

    If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

    However, with the correct details, I get the very plain (Times New Roman):
