Thanks a lot George! For the detailed explanation. While my trials, I did see the “unfiltered_html” capability as deprecated on the User Role Editor plugin and wondered if it was being used by WP or not. All that makes sense now.

And thanks for pointing me towards “Unfiltered MU” plugin. I’ve done a few tests and activating the plugin on one of the sites seems to be working for the Admins editing the raw HTML or inline SVG.

I hope “Unfiltered MU” plugin will continue to work…and will not posses any threats to the site.

Many thanks again!

This issue has come up after WP 5.7 update, where some button classes were deprecated.

Can you please update your code to reflect this change and deploy a new version of your plugin?

Here is an article which states the the old and new classes:
