I followed the installation instructions and verified I had wp_head(); in my header.php and wp_footer(); in footer, but the share slideout was not displaying on my pages. I verified the code was in the page and finally figured out the dcssb.css stylesheet was needed but not being loaded. When I added this stylesheet to my header.php file by hand everything worked as it should. I had to do this on 6 different sites all with different plugins and built from 2 different WooThemes or Starkers themes. I'm not sure if there is something I'm doing wrong or if this is an issue with the current version of the plugin?
