[xwiki-users] Problem to create a new Blog

Hello I created a new blog in a new space according to explanations in the link http://extensions.xwiki.org/xwiki/bin/view/Extension/Blog+Application But the new blog and the wiki blog share the same items. The wiki blog posts are shown in the new blog. And if I create a new article in the new blog, I see it in both blogs. Are there some additional installations or configuration to do? I did not install the WAR xwiki-application-blog. I'am under XWiki Enterprise 3.0-milestone-2.34501 ************************************************************************************************************************** Ce message et toutes les pieces jointes sont confidentiels et etablis à l'intention exclusive de ses destinataires.
