Hello, I had activated the statistics in xwiki.cfg : xwiki.stats=1 xwiki.stats.default=1 But in the Stats space, no statistics are registered. In the config file, we can read : "storage can be enabled/disabled by wiki using the XWikiPreference property "statistics". What does it mean ? I don't have any "statistics" attribute in the XWikiPreferences object. XWiki initially installed in 1.9.2 and upgraded to 2.0.2. Thank you for your help.
