Description of problem: It's seems there is a lack of a symlink to /usr/share/mediawiki/skins/ directory in /var/www/wiki/. Version-Release number of selected component (if applicable): 1.9.4-35.fc7 How reproducible: Always Steps to Reproduce: 1. Install mediawiki via yum 2. Configure it Actual results: After configuration, web pages should respect mediawiki themes. Expected results: After configuration, web pages don't respect mediawiki themes (no images and no CSS, so the display is ugly). Additional info: It seems there is a lack of symlink to /usr/share/mediawiki/skins/ directory in /var/www/wiki/. Adding this symlink solve the problem. Maybe others symlinks are required, but with the skins symlink all seems to be ok.
You don't need to (and shouldn't) symlink anything more to the web exposed mediawiki install, just use Alias /skins /usr/share/mediawiki/skins in your httpd.conf where appropriate.
