PHP & Shortcode Not Working

Hello – love the simplicity of this (especially with the google analytics integration).

After I set up the plugin to show at the ‘bottom’ of posts, I see that it is adding the shortcode to multiple elements in my theme – slider, parallax section, etc. so I then tried to add the PHP directly into my custom post template but for some reason it’s not showing.

I also tried adding the shortcode to the footer and it doesn’t show anything in the area – it remains blank.

Perhaps I am implimenting wrong. Is there an email address where I can send you the URL to my site for a quick look?

Cheers! Thanks for your hard work on this plugin!
