This error became a problem after many desperate attempts to get imagecache working I saw a post that said there were problems with my version of PHP. I was running PHP 5.2.8.
I downloaded the latest stable version of PHP (as of 28/09/09) which is PHP 5.2.11.
It says during the installation that it is not recommended that all features available should be installed by default – this will cause problems! I’m running on 2003 Server (IIS 6.0) using FastCGI. After re-booting my server a few times and adding more bits to my PHP install I saw this error message:

If you are the maintainer of this site, please check your database settings in the

Ok, the solution really is there. It’s in settings.php it’s on line 92 the following code:
If your host doesn’t have mysqli installed, you can it change to use mysql. (MySQLi stands for MySQL Improved.)
Open settings.php change $db_url from mysql to mysqli (settings usually in /sites/default-folder in your drupal installation).
$db_url = ‘mysqli://user:[email protected]/table’;
$db_url = ‘mysql://user:[email protected]/table’;
