Sorry for the confusion - mine. This IS a problem with this testimonial rotator, NOT the DZS one (which won't rotate at all in my installation).
This is running on an XAMPP stack on a Windows server, if that makes any difference.
Everything works fine, but when you refresh a page it shows all posts briefly, then begins to rotate. It doesn't matter if the rotator is inside a plain text widget, in the PHP code widget or where it is. Behavior is the same.
From previous post, that was erroneously marked as Resolved:
I have the shortcode '<?php echo do_shortcode('[testimonial_rotator id=57]'); ?>' inside of a PHP code widget 2.1 widget. When the page first loads only a single testimonial displays and they display in sequence properly. But when the page is refreshed, it flashes the display of all testimonials at once, before then rotating through displaying them one at a time. How do I stop that from occurring on a page refresh?
