How do I enable shortcodes in testimonial content

In your theme's `function.php` file put the following.

add_filter( 'testimonials_widget_content',  'my_testimonials_widget_content', 10, 4 );
function my_testimonials_widget_content( $content, $widget_number, $testimonial, $atts ) {
	return do_shortcode( $content );
}
