[xwiki-users] Cannot rollback history - xwiki-users@xwiki.org

28 Apr 2008

Hi,
I've just upgraded the XWiki of my company from version 0.9.840 to
version 1.3.2 (latest stable version), using the "database copy" method
to copy data. Everything is OK now, but I cannot rollback any page to a
previous version in the history , even if the page is created in the new
installation (1.3.2).
I've got this error:

WARN  web.XWikiAction - Uncaught exception: Error number 3004 in 3:

Wrapped Exception: Error number 2002 in 2: Error parsing xml
Wrapped Exception: Error on line 1 of document  : Content is not allowed

I use a MySQL database (v. 5.0) and Tomcat (v. 6.0.16) as servlet container.
Any suggestion?
Thanks a lot!
