I've decided to give Drupal a try, I installed it via Fantastico but the version it installs is not the lastest version - 5.1 vs. 5.2 (security updates) since I haven't used it I decided to do the upgrade however I get this error message and I'm not sure what it means. The 5.1 install worked just fine btw.
Unsupported database type
The database type is unsupported. Please use either mysql for MySQL 3.x & 4.0.x databases, mysqli for MySQL 4.1.x+ databases, or pgsql for PostgreSQL databases. The database information is in your settings.php file.
For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.
Any suggestions on what I need to do?
