PHP 4.3.11: ok Warning: PHP's register_globals option is enabled. MediaWiki will work correctly, but this setting increases your exposure to potential security vulnerabilities in PHP-based software running on your server. You should disable it if you are able. PHP server API is cgi; using ugly URLs (index.php?title=Page_Title) Have XML / Latin1-UTF-8 conversion support. PHP's memory_limit is 16M. If this is too low, installation may fail! Attempting to raise limit to 20M... ok. Have zlib support; enabling output compression. Neither Turck MMCache nor eAccelerator are installed, can't use object caching functions Warning: shell_exec() has been disabled for security reasons in /home/wikibus/public_html/wiki/config/index.php on line 1328 GNU diff3 not found. Found GD graphics library built-in, image thumbnailing will be enabled if you enable uploads.
