I know this is just a configuration problem, just needing to copy the PHPTAL-NP-0.7.0/libs/ to the proper place, but I can't seem to get it to work. Any help?

MediaWiki 1.3.0beta5 installation

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

Checking environment...

PHP 5.0.0 ok PHP server API is apache2handler; ok, using pretty URLs (index.php/Page_Title) Have XML / Latin1-UTF-8 conversion support. PHP's memory_limit is 20M. If this is too low, installation may fail! Have zlib support; enabling output compression. Found GD graphics library built-in, image thumbnailing will be enabled if you enable uploads. Installation directory: /opt/lampp/mediawiki Script URI path: /mediawiki
