On my Dokuwiki system, upgrading to version 2006-03-09 breaks the content plugin.
When using the "noshowpage" option this results in two nested <a> tags around the page-titles, only one being a link, the other one coming from the original page title. I.e. instead of '<a href="/dokuwiki/doku.php?id=todo:ldap" class="wikilink1" title="todo:ldap">LDAP-Service</a>' i get '<a href="/dokuwiki/doku.php?id=todo:ldap" class="wikilink1" title="todo:ldap"><a name="ldap-service" id="ldap-service">LDAP-Service</a></a>'.
Also, when using the "changelog" option, there is a php error complaining about a missing function "auth_getUserData()".
The attached patch solves both issues for me.
