I noticed I had jquery included by WP and in my header. I removed the version from my header, and the testimonial widget stopped working rotating altogether. It just showed a static list of a random selection, and didn’t change.

This is a new one on me. I guess a previous fix one-way, broke the widget another.

It seems that the original CSS to hide the extra testimonials is missing.

Yup, are you not including the testimonials widget CSS for some reason? If so, you might consider setting

.testimonialswidget_testimonial {
    display: none;
}

You, sir, are both a gentleman and a scholar. Thank you. It works perfectly. I must have missed the step where you have to link the widget’s CSS in the template source code.

You’re welcome. The CSS should be automatically included when activating the plugin. However, your theme might be unsetting that call.

add_action('wp_head', 'testimonialswidget_css_head' );
