# 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?
 * Thanks,
    Ed

 * 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.

 * Also, try reviewing the following codex for possible reasons and solutions: [http://codex.wordpress.org/Common_WordPress_Errors#Error_Establishing_Database_Connection](http://codex.wordpress.org/Common_WordPress_Errors#Error_Establishing_Database_Connection)

 * Thanks both. [@sterndata](https://wordpress.org/support/users/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):
 * > Error establishing a database connection
