version 4.0.6 of the plugin 'Sociable' doesn't work when using '%sociable%' in the footer due to a change in the plugin's code. It can be fixed by changing line 474 of bfa_postinfo.php from
function_exists('sociable_html') ) ? $sociable = sociable_html2() : "" );
to
function_exists( do_sociable() ) ) ? do_sociable() : "");
