Like other reviewers, this plugin did nothing but blow up my site, most likely because it conflicted with other plugins or the theme (Enfold, which is extremely common). I was not able to access any admin functions, so I tried to delete the shortcode plugin folder via FTP. Still dead. I deleted ALL of my plugins and the plugin folder itself, and reinstalled everything from scratch. Site works again but at half the speed of before.
Avoid this plugin at all costs.
