Sorry Frank,
now I realised that I have to activate the checkboxes for the post-editor.
Now it is working.
But why are these checkboxes not aktivated by default? It’s a little confusing.
Unfortunatly the new version 2.2.0 from today does not work at all in my blogs in the code-editor.
Not before I save the draft and not after I save it.
I even deinstalled the plugin and reinstalled it. But it does not work.
Please fix it Frank.
