I have some problems with quizzes :
When viewing Detailed Statistics of a quiz completed by 0 user (I know it's silly but...) I get the following warnings :
Warning: Invalid argument supplied for foreach() in /var/www/html/moodle/mod/quiz/report/fullstat/report.php on line 93
Warning: Invalid argument supplied for foreach() in /var/www/html/moodle/mod/quiz/report/fullstat/report.php on line 105

On a quiz that has been completed by several people, I guess
the table "Listing of Items in Quiz with Summary Statistics" should
list how many people (in %) proposed a given answer ( for instance :
10% chose answer 1, 80% chose answer 2 and 10% chose answer 3 ).
However I only get 0% statistics...Warning: Invalid argument supplied for foreach() in /var/www/html/moodle/mod/quiz/report/fullstat/report.php on line 105

I hope someone can help
