Error when trying to updated any page "This page needs a refresh."

Anytime we try to update a page we get the message "This page needs a refresh. You’ve probably updated this page (or another page) in a different tab or browser."

This is for https://peaceathome.com/

Brizy version 2.8.9 is installed

Brizy Pro version 2.8.4

Wordpress 6.9.4

All other plugins are disabled. I have also switched to the default 2025 WordPress theme to eliminate the theme as an issue.

I have cleared my cache and tried both Firefox and Chrome.

I found I post saying that the Brizzy and Brizzy Pro need to be the same version so I found Brizzy 2.8.4 on github and that also did not fix it. That actually lead to a critical error and I had to restore a backup.

I found this guide now, that is talking about ModSecurity in cPanel, but we do not have that. Would Immunify 360 be causing this error?  https://support.brizy.io/hc/en-us/articles/22590197512210-How-to-fix-the-error-This-page-needs-a-refresh-You-ve-probably-updated-the-page-in-a-different-tab-or-browser

Decided to work on the WHM side and was able to update ModSecurity with the terminal. Brizzy appears to be working now.
