Works Everywhere but not on 1 Page (works only in Safari )

Love this plugin. Its great. Ok, so the thing is that it works everywhere on the site except one page, but that particular page it works in Safari, nothing else. Riddle me that.

If you look at it in Safari you will see it twice at the bottom of the article. One from the plugin on its own one from me putting the code into the article itself.

Any insight would be great, thanks!
