Expand / Collapse Not Working Since Update

Hello Accordions,

I received the Wordfence notice about potential vulnerability so I upgraded to the latest version in our test environment today.

Here's a direct link to an accordion on our test site: https://wip.tradeclassics.com/accordions/2380/

Since the update the accordion is expanded by default and you can't collapse it.

I've tried changing all basic settings hoping that might work but it doesn't.

It's the same for all accordions on the site.

Please can you look into it and let me know.

Thanks

Adam
