Popup title: "Save your changes"
I tried to refresh the page or choose different options in the popup showing up when hitting "Save changes" button.
If I edit an article and try to save it all on the same day, it works fine. The issue seems to be when I edit an article on a day X, turn my machine off, and on day X+1, I try to save the article with my changes having been automatically recovered: that's where the issue occurs, and I can't save the article in this case.
