Hi all,
I've made an upgrade from SD 0.7 to SD 0.8
Unexpectedly I got this Fatal Error: 
Call to undefined method SMWStringValue::getXSDValue() in /var/lib/mediawiki/extensions/SemanticDrilldown/includes/SD_Utils.inc on line 155
after some research and tentative I realized that my LocalSettings pointed at 
 instead of 
Then I made the amendments but now the DrillDown does not work, i.e. in the Special:BrowseData page I get the different items corresponding to the (filtered) properties but no articles
I just replaced the old 0.7 directories system (under /var/lib/mediawiki/extensions) with the new 0.8
Did I make a mistake or miss something?
