We are running MediaWiki on a Windows Server at http://www.relisoft.com/wiki - MediaWiki 1.5.4 - PHP 5.0.5 - MySQL 4.0.18-nt First problem: When I access it from one of my home machine, I see a completely blank main page. Other people can see the full page. I can see some of the other pages, if I specify the title. Second problem: I get the error: Undefined index: REQUEST_URI in includes\WebRequests.php, line 284. This is the offending line of code: /** * Return the path portion of the request URI. * @return string */ function getRequestURL() { return $_SERVER['REQUEST_URI']; } Is this a problem with PHP/MediaWiki mismatch?
