[Mediawiki-l] Setup problems (Redefined constants/blank page)

[Patrick Aland]

I'm attempting to setup Mediawiki 1.3.8 on an OpenBSD 3.6 box running
apache 1.3.33 and MySQL 4.0.18

When I first try to install it after filling in the information on the
config/index.php page I get the following:

MediaWiki 1.3.8 installation
Please include all of the lines below when reporting installation problems.

Checking environment...
PHP 4.3.9: ok 
PHP server API is apache; ok, using pretty URLs (index.php/Page_Title) 
Have XML / Latin1-UTF-8 conversion support. 
PHP is configured with no memory_limit. 
Have zlib support; enabling output compression. 
Found GD graphics library built-in, image thumbnailing will be enabled
if you enable uploads.

If I edit the config/index.php and specify absolute paths for the 3
require_once statements instead of the default ../includes setup
completes.
However when I go to what should be the front page I just get a blank page.
Any ideas? PHP is set to log errors (I've got a page missing a ; just
to test that error logging is in fact working) but viewing the wiki
main page doesn't log anything.

Thanks
