Hello,
I found that the button to admin page disappeared.
User which i used have admin rights.
If i use direct link “http://xwiki/bin/admin/XWiki/XWikiPreferences” - it works.
but in right-top menu there is no this button
When i remove Administation Application from extention manager and reinstall it - button on its place. After xwiki reboot - it disappears again.
As i remember, I didn’t configure anything at last time, some times ago - it worked. my xwiki version 9.9. I tried to upgrade xwiki and its extensions to the latest version, but situation is the same…
Help, please/
