If that’s not checked, then This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

Thats not the cause. I checked all users and its unchecked like in your pic.
All my other wordpress sites are ok. I did notice some small changes in the editor today though…was there an update somewhere ?
For example adding a link, im sure the editor displays a slightly different graphic.
