Any chance this was figured out?
I’m having the same error. It’s a new site and I was using this on my first post, so I went ahead and deactivated all plugins. I still had the error or errors. I have to close the page as the popup either keeps popping up or there are 1000’s of them.
I was running php7.2, I changed it to 7.4 to test and got the same error. I’m in Chrome with the newest WP version, and originally was using genesis and a child theme. For testing, I went back just the 2020 theme and I still got the error.
I love the idea of the plugin. Please let me know if you need any more information from me and thank you for creating this and your work on the plugin.
