Hi Brion, thanks to answer. The output from config - install after sending data is: MediaWiki 1.3.0 installation Please include all of the lines below when reporting installation problems. Checking environment... PHP 4.3.8: 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 40M. 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: /homepages/15/d16081958/htdocs/Wiki Script URI path: /Wiki Thats all. No report for any error. I have test it by two German hosters - Schlund and 1+1. No difficult result. Local at home is running under Linux without problems. In the diskussion in 07/04 i have read from problems with memory_limit. Is this the problem broken the install by hosting install? Regards Dieter
