We have the same problem in ZUM-Wiki
(
www.zum.de/wiki). We miss the "Mail to
user" link, since we upgraded from MediaWiki version 1.3.6 to 1.4.0. So it
seems to be a "problem" or a different configuration of version 1.4.0.
*Upgrade to 1.4.5 immediately!* You are vulnerable to several security
vulnerabilities.
