Hi all, We are trying to upgrade our XWiki from 4.0 to 5.4.1, but we encouter some problems: 1) The Activity Stream is not working any longer. It just says "There are no activities in the stream". No errors as far as I can see, but creating a new page (or updating a page) does not show anything in the Activity Stream. 2) We used to use the Navigation Menu Wiki Macro <http://extensions.xwiki.org/xwiki/bin/view/Extension/Navigation+Menu+Wiki+Macro> together with the Navigation Menu Config Application <http://extensions.xwiki.org/xwiki/bin/view/Extension/NavigationMenuConfig> in our XWiki 4.0 Now with 5.4.1, we want to use the Menu Application <http://extensions.xwiki.org/xwiki/bin/view/Extension/Menu+Application> , but the Menu Application is not showing the "Menu Structure" (that section is empty, even though I have pasted our old menu). The "Inline-form" is also showing nothing, but the WYSIWYG and the Wiki editor DOES show the menu. Also, on my computer, I have a nice gray background, but that background is missing for all the other users. Any clue how I can "restore" the background for the other users? -- View this message in context: http://xwiki.475771.n2.nabble.com/Upgrade-trouble-4-0-to-5-4-1-tp7589257.ht… Sent from the XWiki- Users mailing list archive at Nabble.com.
