Issue with Most Popular(Most Commented) not Working!

Please, in yuzo widget, when I set:

“Use Yuzo Widget as” to “List Post”
and “Show (Select list you want to show)” to “Most Popular(Most Commented)”,

the widget does not display in my sidebar.

Please, look into this issue.

Regards,

Stardrive
