Wysiwyg editor blank preview after WP 7.1 update

Hello,

I’m having an issue with ACF Pro.
I use about about ten WYSIWYG instances for a custom field. Everything was working perfectly until the WordPress 7.1 update. Now, when I edit a post, the WYSIWYG editor previews are blank. If I switch one of the editors to “code” mode, the code displays correctly, but if I switch back to “preview” mode, the content is still blank.

Has anyone else encountered this problem?

Thanks in advance.

Hi, I’m having the same issue on several websites, but I’m not sure exactly when it started or what’s causing it. Is there a fix for this yet?
