 * Hello, today it just happened and i just can’t get any clue about it, error: **
   Error establishing a database connection**. Built this blog like 1 month ago 
   and no problem since then, yesterday i even updated it and there were no problems.
   Today when i woke up i saw the error and started checking wp-config file, settings
   are all correct, no changes but still blog doesn’t work, i even built a small
   php file that checks the connection to the database and it told me: connection
   established. You can check the error here: [ Cars 321
    Please need a help hand
   here or i’m ruined.

 * to start with, try:
 * 1. checking with your server for any problems at their end.
    2. checking your
   wp-config.php file to make sure the domain info there is current and valid. 3.
   If you have access to your database, in the wp_options table, make sure ‘siteurl’(
   should be record 2)is set to the correct domain.
 * **Backup your DB before touching it **
