Thread:Project:Support desk/1.17 upgrade failing when upgrading database

Hi all, I'm trying to upgrade mediawiki from 1.16 to 1.17 but whenever I get to the "Upgrade existing installation" step it creates a 500 internal server error.

Here are my versions: PHP version 	5.2.17 MySQL version 	5.0.91-community-log

When i visit mw-config/index.php again it just says the installation is complete even though the changes to the database were not made.

I'll leave the url of the wiki out for the meantime since all the issues are done on the installation step. Any help will be much appreciated.

Thanks
