Crashing while editing certain content

Hi,

I just recently updated to the newest version of cornerstone. When editing a testimonial block on a page I am getting thousands of these errors which eventually make the page go unresponsive:

react-dom.min.js?ver=16.13.1:125 DOMException: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node.
at HTMLDivElement.insertBefore (<anonymous>)

What do I need to do to fix?

Hi Rob,

Thanks for reaching out.
It might be due to the improper up-gradation of the Cornerstone plugin. I would recommend you install the latest Cornerstone once again by following the below steps.

1. Delete the Cornerstone existing one
2. After deletion of the Cornerstone, please use the link in the dashboard to automatically install the Cornerstone.

If that does not help and you are still getting the issue, please provide login credentials for your site in a secure note to examine it further, including:

– WordPress Site URL & Login URL
– WordPress Admin username/password

To create a secure note, click the key icon underneath any of your posts.

Thanks
