This may be a plugin or theme conflict. Please attempt to disable all plugins, and switch to the default Twenty Twenty theme. If the problem goes away, enable them one by one to identify the source of the problem.
If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.
I have install health check and disable all plugins, but it doesn’t change anything.
I think it may be theme conflict, but this theme has been modified many versions.
I don’t know how to fix the conflict.
Do you still have the same problem with the Twenty Twenty theme enabled?
I found that is a class “mceContentBody” caused it.
When I remove it in the HTML, it is normal.
I have disabled all my plugins, the “mceContentBody” seem to belong to Tiny MCE.

Interesting, if that were the case all on its own though, there would be far more than just this one report.
Does the issue continue with all plugins deactivated, and only the Twenty Twenty theme in use?
I’m in the Troubleshoot mode.
And it also appears.

Description: Used to style the TinyMCE editor.
