Problem with shortcode on index.php

Hi!
I recently use you plugin on my site. I tested the plugin on a normal page, all OK. But I want to put the slide in the homepage, puting the shortcode into index.php code but isn’t work, are don’t showing the slide, instead are show the shortcode as simple text.
I already prove a few ways to make the shortcode work on index.php but still isn’t work.
How is the way to put the slide on index.php to show it in the homepage?
