To repeat the subject expanded (since the Subject field here is way too limited as far as character count!):
Suffusion "Query Users" widget treats all "Order by" settings as apparently "Display name" so say "Order by" "post count" (key to listing which users have the top # of posts) is impossible (instead always appears sorted by "Display name").
I Google Searched for the problem but didn't find any posts on it (in fact I didn't even find any docs on the widget besides http://aquoid.com/news/themes/suffusion ... hment_1172 ).
Searching the source code http://themes.svn.wordpress.org/suffusi ... -users.php doesn't easily show the problem & fix (without carefully examining the code).
I observe this at http://1.JotHere.com/87#M7AKDD so running latest WordPress 3.4.1 in Suffusion “version 3.9.6” and latest 4.2.5.
As a random thought, perhaps it worked in earlier versions of WordPress but with WordPress's recent database upgrade, it's not working anymore.
Please help else I'll have to find & get some other widget.
