woocommerce tabs not open with activated plugin

Very very very unlikely to be just the plugin being active. It has no javascript and is actually VERY simple in what it does.

That said….

– who knows what the widgets are doing that are being shortcoded. If they are outputting js then they are maybe breaking something when used in a shortcode.

Try looking at other people’s solutions when they had this problem

To satisfy yourself that it is NOT just the plugin being active, remove all do_widget shortcodes from the page and refresh any cache etc. I’d be surprised then if just the plugin being active still causes the problem.

Do post back and let us know.
