Short code in echo do_shortcode( not working

Hello,

I have been trying to get plugin shorcodes to work within my template instead of just in posts/pages. All my shortcodes work within a post or page.

As soon as I try to call the shortcode from a plugin through

<php? echo do_shortcode('[]'); ?>

Nothing loads. I have tried turning off all other plugins and tried it using a number of different plugins. I think the problem is with the echo do_shortcode() in my site.

Can anyone shed and ideas what the problem might be?

I have also tried to load the shortcode by creating a page with it installed in. Then referencing the content of that page in my template but can’t get that to work either.

Any help greatly appreciated.

I was originally trying to get the following plugin to work, but have since discovered that all plugin shortcodes wont work with the do_shortcode.
