Hello, I installed on my linux laptop the xwiki enterprise: i installed the war, the xar, i added the plugins for the wiki-manager and application manager, the both applications and the XAR to load XEM pages. Everything is ok and i can do all i want in it with panels or logout. Then i created a virtual wiki (without any template as none was suggested) and in this virtual wiki i installed the xar from the wiki enterprise. In this virtual wiki, if i want to log out i can't (i have to logout from the main wiki) . Also i try to move the Search panel from right side to left side then after a refresh, it's replaced by another panel (list of panels or the panel called "Main") even if i recreate the search panel in a SearchPanelBis. And now i can't do anything with panels i always have the problem. I have to reload the XAR (and get the search panel on the right) if i want to have it working I can't find out why i have this problems on a virtual wiki and not on the main one.
