editing pages: displaying/publishing source code

Very strange thing happening here. I have updated to the latest Divi (theme) and WP and the problem persists.

I am the super admin for this multi-site installation. Everything was working fine and dandy, editing existing pages, until this last update.

When going to edit a page in the backend, I am seeing code in the Visual editor. When making an edit, and previewing, I am seeing the code, not rendered. Same when published.

This was NOT happening before the update.

I am attaching an image of what it looks like in the Divi editor as well as preview.

Any insight would be appreciated.

Thanks,
