 * Error connecting to your database:
    In nutshell, you’re getting this error because
   WP is unable to establish a database connection. Reason why WP is unable to establish
   a database connection can vary. It could be that your database login credentials
   are wrong or have been changed. It could be that your database server is unresponsive.
   It could be that your database has been corrupted. Majority of the times this
   error happens because of some sort of server error. Also, there could be other
   factors as well. To troubleshooting this problem: – double check your [wp-config.php file settings ](http://codex.wordpress.org/Editing_wp-config.php)
   for the database name, database username and database password, and the host 
   name (e.g., “localhost” Vs. something else). This is where most errors occur.–
   Then make sure wp-config.php is in right location. – 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. Contact your hosting provider if the database server is offline(
   if the problem suddenly happened), or if they have any other problem at their
   end, or they made any changes to your account, or if there are any limitations/
   restrictions, or if the hosting package is set to Windows and not Linux, etc.–
   If the error is intermittent then it’s your server. What’s happening is that 
   the web server and/or the database server are gettign overloaded and the connection
   is droping out or is refused for a short time. That gives you the database error
   as the website can’t connect to the database. To fix this, you’ll need to talk
   to your hosting company as they are the only ones that can do anything about 
   hardware issues like this. – There are also many threads on this topic on these

    I fthe
   aboe does not help, my suggestion would be to start your own thread to get full
   attention to your specific issue. Despite any similarity in symptoms, your issue
   is likely to be completely different because of possible differences in physical
   servers, accounts, hosts, plugins, theme, configurations, etc. Thus one problem,
   on one setup is not indicative of the functionality and reliability of an application
   as a whole. So, to get the best attention to your specific issue as you deserve,
   please review how and where to post in this forum: [http://codex.wordpress.org/Forum_Welcome#Where_To_Post](http://codex.wordpress.org/Forum_Welcome#Where_To_Post)
