[Mediawiki-l] HTTP 500 error after installation

[Hagix]

Hi,

I managed to install TikiWiki without a problem and now I want to install
MediaWiki as well in order to compare both systems. I FTP'ed the unzipped
MediaWiki files'n'folders into a new directory on the remote server,
chmodded the "config" directory and its index.php to 777. But when I'm
browsing to config/index.php I'm getting an HTTP 500 / Internal server
error.

PHPInfo says:
PHP Version 4.3.4
Linux 2.4.21
mySQL 4.0.15

Any ideas what to do?

Thanks,
Hagix
