User cant comment

Guests can comment but user only if i select “moderate_comments” on.

Hello why dont help me?

Any logged-in user even subscriber can comment by default.

I suppose that comments functionality was changed some way by the active plugin or theme. Try to deactivate all plugins and switch to the 2016 theme. If it will resolve the issue, activate plugins back one by one to isolate the problem. Or start from the theme.

No all plugins deactivaded and 4 themes testet!

Comments only works if is “moderate_comments” on!

Did you test this with other fresh-installed WordPress installation?
Pay attention also on the ‘must-use’ and ‘dropins’ plugins which do not require activation and (if presented) still may modify the default WordPress functionality.
I suppose also that some core WordPress files may be modified at that instance.
