Hi Karsten,

Most likely the webdav module (not the plugin but the server) uses /pages
for instead of /spaces. You can verify this by connecting to your xwiki
server with a webdav client as guided in
http://dev.xwiki.org/xwiki/bin/view/Drafts/WebDAV. If you see a 'pages' view
instead of a 'spaces' view, you might want toupdate your webdav module.
You can do this by erasing your
/webapps/xwiki/WEB-INF/lib/xwiki-webdav-**.jar file and replacing it with
one from
http://maven.xwiki.org/snapshots/com/xpn/xwiki/platform/xwiki-webdav/1.8-SN…
But this requires you to restart your xwiki server.
