[xwiki-devs] Xwiki 2.0 migration problems

Hello friends! I have migrated xwiki testing instance from 1.8 to the 2.0 http://test.odo.lv:8180/xwiki/bin/view/Main/ I could import XAR 2.0 only using hack with stopping 2.0 instance, and ran updated DB with 1.8 web instance, imported XAR, and svitched back to web 2.0. It worked previous times. Though currently there are many regressions: 1. Can't choose different view/edit modes from the menu, only default ones ar accessible, as drop-down menus aren't shown, 2. Can log in only with superuser. Using other users Xwiki says: "You are not allowed to view this document or perform this action." 3. Cannot edit neither groups, nor users. When form is opened, it stills with progress bar and "Loading..." message. 4. Site index doesn't work. In summary it seems, there ar bunch of pages where either Javascipt doesn't work properly, or there is global problems with page access. Site is multi lingual, there are lot of custom objects in some spaces. I couldn't find anything interesting in tomcat logs. Can you point some directions, what to check and investigate? Thanks in advance, Valdis
