How to get rid of the quotation marks that surround the random quote

Check ‘Hide built-in quotes?’ on the General tab of WP Admin > Testimonials > Settings page or widget options. Alternately, try `disable_quotes=true` in your shortcode.

See attached for where to disable and how to alternately style.

Before version 2.11.0, in your theme’s custom.css or styles.css file write the following CSS.

.testimonials-widget-testimonial .open-quote:before,
.testimonials-widget-testimonial .close-quote:after {
    display: none;
}
