Hello, after setting up the basic xwiki(4.3.1)/db stuff i went on and installed some of the features from the xar file. Afterwards I was asked to authenticate, but every page I tried to load just never ended loading. After restarting tomcat and waiting for some minutes I was able to reach both the Main page as well as the Login page and successfully logged in as Admin. Now the pages won't load again. Is that a known problem? Any ideas on what i could try to get the system running again? Thilo
