Suddenly stopped working

I uploaded the WP Socializer plug-in yesterday, and it was working fine (i.e I used the one click ‘simple template-comact-inverted’). This morning the layout was skewed in that the buttons appeared in a vertical row from the top of the post (some condensed), pushing all the content down. The only thing I did in between was add a favicon (via the header.php – so I don’t see how this would affect it). I tried deleting the plug-in then reloading, but it still does not work. I also tried to use the placement mechanism – the only button that works is the “facebook-like” (the none of the others even show up). Ideally I’d like the “facebook-like” and “sharethis-bt” at the bottom of each post. Please let me know if you have suggestions. Thanks
