Your provided link is incorrect - it leads to Bad title special page. However, you are talking about this article, right? The " " error appears there because that page, just as the error indicates, lacks  tag despite that a citation is used there.  is important to be added at the bottom of page where citation is used - otherwise, not just there would be no footnotes list, it would also cause such error. Hence, to fix the issue on page in question from your wiki, just add  on the end of page.
