I forgot to define <ref=Onxley> and when I used <ref=Onxley/> there was no error message. Just a blank line after the reference. https://en.wikipedia.org/w/index.php?title=User:Vchimpanzee/Central_Elementary_School_%28Albemarle,_North_Carolina%29&diff=prev&oldid=607783096
When the error messages were first implemented, they showed on all pages and there were a lot of complaints. The English Wikipedia implemented customized error messages. {{Broken ref}} controls the error messages and uses namespace detection. By default error messages do not show on user and talk pages. See {{Broken ref}} for CSS to show error messages on all pages.
Not a bug; this is due to implementation on enwiki.
