Hi I got the same problem and was because i missed some new files in the Xwiki space. Did you follow the migration instructions on the Xwiki site ? And did you updated pages using the new XAR ? -----Message d'origine----- De : users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] De la part de Mohamed Arrass Envoyé : vendredi 15 mai 2009 11:08 À : users(a)xwiki.org Objet : [xwiki-users] XWiki Enterprise 1.83/1.82 . User and GroupAdministration 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. _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users -------------------------------------------------------------------------------- This e-mail is intended only for the addressee named above.
