Only white space appearing – No error message

Hi there,
I seem to have run into an issue with your plugin.

When trying to create any kind of chart using the following shortcode on any page, I am only getting white space where the chart is supposed to be and the advertisement link to your site at the bottom:

[gfchartsreports gf_form_id=”10″ height=”500px” gf_entry_id=”last” count_answers=”1″ group_fields=”1″ include=”1,2,3,4,5″ type=”radar”]

I used simple number fields and even tried to rename them or create admin field labels, but nothing worked.

I feel like there is an easy solution to this, but I am just not seeing it…
