ah crap, yes there were other changes to that set that would have thrown an error, sorry thought that would be a quick fix.
there should be a full release this week, other wise you can look around line 279 of the snippet for the "array_multisort" line in the else statement and comment it out so it looks like the following:
// Sort the data with volume descending, edition ascending
// Add $data as the last parameter, to sort by the common key
if(count($arrEventDates) && $displayType == 'list'){
if($dir == 'ASC')
array_multisort($date, SORT_ASC, $event, SORT_ASC, $arrEventDates);
else
array_multisort($date, SORT_DESC, $event, SORT_DESC, $arrEventDates);
} else {
//array_multisort($date, SORT_ASC, $event, SORT_ASC, $arrEventDates);
}
sorry for the confusion
