GPP Accordion Not Working

Everything else from the GPP Shortcodes plugin is working fine, like the buttons but anything with movement (accordion, toggle, etc) isn’t.

When it comes to troubleshooting plugins, I’m a little green. If you tell me it’s an issue with JQuery, please take a moment to talk me through the steps.

Any help would be awesome!
