[Plugin: GPP Testimonials Widgets] shortcode not working

Hi,

Hopefully someone can help.

Instructions state if you wish to add testimonials to your page, then there is a blue icon in editor you press which produces the short code.

The editor shows short code but when I publish and refresh website it does not appear on the page? Although it still appears in the editor?

The plugin has a widget option which I have tested and this works fine. But i would like testimonials to appear on my page.

This is the short code
[testimonial name=”Olivia K” about=”test” url=”http://calligraphycompany.com” image=”www.calligraphycompany.com”][/testimonial]

it should be displayed on my homepage . calligraphycompany.com

I have refreshed and deleted cache numerous times.

Can anyone shed some light on this?

Thanks
