Hey Tom!
Ah – that makes sense! If you are displaying the short testimonials and have the Read More link click to the full testimonial, our software falls back to the WordPress template structure (which means it is using your theme’s single.php to render the Testimonial.)
If you want to customize this view, create a single-testimonial.php and then you can do things like begin displaying the custom fields.
I believe, by default, single.php is not displaying custom fields in most themes.
I could see this making sense to display the same HTML block that our plugin displays. You could achieve this by loading the ID of the testimonial, on single-testimonial.php, and then using the function
outputSingleTestimonial($atts('id' => $testimonial_id));
Something like that should work — we don’t have the documentation for customization like that built out very well, at the moment.
I hope that helps!
Best,
Richard
