Extensive work done in the plugin’s default stylesheet (/css/mstw-bb-styles.css). The tournament brackets display beautifully in my development theme (a WP Twentyeleven child theme). See http://dev.shoalsummitsolutions.com/t-test/. Some CSS work may be required for your theme. The primary driver is the width of the bracket’s containing element. It should be at least 750 pixels wide for basic single elim brackets and 900 pixels wide for double elimination brackets with consolation games.
Fixed bug that displayed -1 in the League column of tournaments table on the Tournaments screen when no league has been selected.
