Error when someone try to go to a category
I have an error when I try to go to a category View through a menu Link when I'm not registered. When I'm registered I havn't the error and I can go to the category. This is the error i get:
0 - Argument 1 passed to JoomlaUtilitiesArrayHelper::sortObjects() must be of the type array, bool given, called in /www/components/com_communitysurveys/models/category.php on line 326
I don't know if it's a joomla error or not?
