The Shortcode [phpleague type=fixture id=xx] which can be added via the PHP button lookup to pages or posts, has stopped working.
Sorry, I am unable to say if this happened after WP 3.5.1 update or after the latest PHPleague 1.4.7. As I only just noticed it.
Check out this page of my blog for an example http://atlanticleague.co/atlantic-league-results-2-3-february-2013/
Below is an extract from the content I have entered in the WP admin editor for this page:
Results - 2-3 February 2013
