Error establishing a database connection

  • Hi guys,

    I installed W3 Total Cache and was updating its settings and when I was at the page cache settings and clicked save suddenly I get this error message:

    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.

    I don’t know what happened. Please help!

    Error connecting to your database is common, but it isn’t necessarily a problem with wordpress itself.
    – double check your wp-config.php file settings for the database name, database username and database password. This is where most errors occur.
    -Then check that you don’t need to change the database host from “localhost” to something else. You can get that info from your hosting provider.
    -Check you have actually created a database with the same database name as is in your wp-config.php file.
    -Last, but not least, if all that information is correct your database probably has a problem with it, and you may need to contact your hosting provider if the database server is online / if they have any other problem at their end, or they made any changes to your account, or if there are any limitations/restrictions, if the hosting package is set to Windows and not Linux, etc.
