[xwiki-users] Page redirecting automatically to XWikiPreferences

Hi all, Something really wired is hapening. We have a page that used to list all our speakers (http://www.parisjug.org/xwiki/bin/view/Speaker/). It contains the following code : #set($query="where doc.web='Speaker' and doc.name!='WebHome' order by doc.title desc") #set($results = $xwiki.searchDocuments($query)) #foreach ($item in $results) #includeInContext($item) <br/> #end It always worked well. But now, when we click on the link, we are automatically redirected to the XWikiPreferences pages. I've tried to show the history of the Speaker/WebHome page, but it's impossible, it redirects to the XWikiPreferences page. I'm not sure there is anything wrong with the code of the page, maybe rights issue or something like that. Do you have any idea ? Thanks, Antonio
