Plugin not displaying any icons

I’ve been using this plugin on several sites for a couple of years and it’s worked fine … but all off a sudden all I’m seeing is the bar and none of the icons. Happening on all my website (eg theprooffairy.com and onelifeyourlifeloveit.com) and also on the developers own site: http://www.searchtechword.com/2011/06/wordpress-plugin-add-twitter-facebook-google-plus-one-share/

Any idea when it will be fixed?
