[xwiki-users] Few problems upgrading from 4.X to 5.4

I recently upgraded our wiki to 5.4 from 4.X installation. I used the same database and ran the migration process. All the pages work fine, but i was left with some issues I was hoping to get some help with. 1. Document tree no longer works. I get a 404 while getting /spaces?r=somenumber and wiki shows error : Server returned TRANSPORT_ERROR with no error message. 2. I cannot modify panels correctly with panel wizard: If I add a new widget to the panel, others may disappear. Or when I add a new widget, 3 widgets may appear, the same 3 every time. 3. Cannot update/uninstall extensions All the extensions I had in the old wiki are shown as installed, but when I try to uninstall them, I get an error saying that they are not installed. So if anyone has come accross any of these issues and has found a fix/workaround for it, I would be grateful to hear of it. -- View this message in context: http://xwiki.475771.n2.nabble.com/Few-problems-upgrading-from-4-X-to-5-4-tp… Sent from the XWiki- Users mailing list archive at Nabble.com.
