0 DB_ERROR_NOT_CONNECTED

What do I do with this message?

DB_ERROR_NOT_CONNECTED occurs when something is wrong with your database.

Possible Causes:

  1. Your /includes/configure.php and /admin/includes/configure.php files contain settings for the database (DB_SERVER DB_SERVER_USERNAME, DB_SERVER_PASSWORD, DB_DATABASE, DB_PREFIX), which are used to log in to the database.

    The 0 DB_ERROR_NOT_CONNECTED error occurs when those database settings no longer match the actual details for the MySQL server, the MySQL database, or the MySQL user+password, or if the database server is broken for some reason.

    Or, if you recently changed your MySQL user/database/password and didn’t put those same changes into your configure.php files, you’ll need to update your configure.php files to match what’s required by your MySQL database server.

  2. Some frequently updated tables (such as sessions or whos_online can become corrupt, and cause this problem. Run a “repair” on the database. Most hosts have a Database Repair option listed beside the database names in the webhosting control panel. Ask your host if you need help finding this.

  3. Talk to your hosting company to determine whether they are doing some sort of maintenance on the database. Tell them that your website cannot connect to your MySQL database, and ask them for some assistance in getting that working again.
