Thanks! In the mean time I discovered that Internet Explorer (11) is not really handling this very well. In Firefox or Google Chrome everything works just fine. So now, when I want to work in the Dashboard, I avoid IE…
I’m new here. I noticed that your website now has a wider center column than the standard one in TwentyFourteen, which has a lot of white space left and right.
I managed to change the width for my posts (css in child-theme), but the space in the editor (on the Dashboard) remains pretty narrow. So now, it no longer corresponds to the width of my posts. Any help to solve that would be very welcome.
