Thread:Project:Support desk/Invalid Database Type Error During Installation

Hello,

I keep getting a puzzling message when I run the MediaWiki ( V 1.21.1) installer. It says "invalid database type" even though I'm running a very recent version of MySQL (Ver 14.14 Distrib 5.5.32, for debian-linux-gnu (x86_64) using readline 6.2). Everything looks fine in MySQL itself: database is there, user has the right privileges. Same for the MW folder, itself: owned by www-data:www-data with 755 all the way down.

PHP is version 5.3.10-1ubuntu3.8 with Suhosin-Patch (cli).

Could this PHP Warning be significant, though? Module 'pdo_pgsql' already loaded in Unknown on line 0

Here is the URL: https://pharos.braintec.ch/mediawiki/

Thanks in advance for any help you're able to offer. I've reinstalled MW several times, dropped and remade the database, even reinstalled MySQL, but still no luck.
