Hi Vincent, I repait it without XAR!
I open my subwiki (where admin ui work correctly) page /XWiki/XWikiPreferences?editor=object in object editor and open this page in my Main wiki. I compare pages and delete all object which not present in /XWiki/XWikiPreferences in my subwiki. After this - admin ui works correctly on my Main wiki! (I think that some old objects broke admin UI) Thank for help! -- View this message in context: http://xwiki.475771.n2.nabble.com/Problem-with-update-from-7-1-2-to-8-4-1-tp7601982p7602501.html Sent from the XWiki- Users mailing list archive at Nabble.com.
