My wiki's short url is
When I visit Special:Notifications,that is
//domin/wiki/Special:Notifications, the page prompts me "No such special page". After that, I visit it with another url(//domin/w/index.php?title=Special:Notifications), the page can be displayed properly.
Once, I thought it was web server url rewriting problem. However, most special pages are still accessible. So, I think the mediawiki have a bit of a problem.
