[xwiki-users] XWiki Enterprise 1.83/1.82 . User and Group Administration

Hello, since we upgrade on Version 1.82 We can no longer administrate the users and groups in the admin Interface, we test it with safari firefox. I update to1.83 but nothing changes. I debug the xwiki user and group interface with firebug. They show me the following error when i open the user and group config interface GET http://SERVER/xwiki/bin/admin/XWiki/XWikiPreferences?editor=globaladmin&… ASSTable is not defined XWikiPreferences?editor=globaladmin&section=Users() ()XWikiPre...ion=Users (Linie 318) [Break on this error] var ta = new ASSTable("?xpage=get...r1", "userstable", displayUsers, true); When i go to the users and group interface, they show me a loading bar. But the Client request is finished.
