Newest-Active-Popular Member showing vertical

All of sudden, the thumbnails of Newest-Active-Popular members started to show up vertical instead of two-lines horizontal it used to be like before.

The problem is on http://prasaifamily.org

It started without any editing on theme files. Suspect after Wordpress 4.2.2 update but please suggest how this can be fixed.

Hello,

Please update your theme to the latest version, because this problem is already fixed.
