The problem is that Blizzard changed GetQuestLogTitle(n): they removed the 3rd return value:

questTitle, level, questTag, suggestedGroup, isHeader, isCollapsed, isComplete, isDaily, questID, startEvent = GetQuestLogTitle(questLogID);

This means that all the code that tries to get the questID:

local name, _, _, _, _, _, _, _, id = GetQuestLogTitle(i);

will now be off-by-one; and the id will actually contain the startEvent flag (a Boolean value).

The fix, in three places, is to change:

From: local name, _, _, _, _, _, _, _, id = GetQuestLogTitle(i);
To:   local name, _, _, _, _, _, _, id = GetQuestLogTitle(i);

removing one of the variable placeholders.
