<p>Hi, I know I'm not an administrator but I think I can help ...
To not lose the progress you have to save it,
if you are creating an article by <i> edit souce </i> mode, to save it just click on the icon <i> publish </i> (underneath a drawing of the computer on the page)
.if you are creating in another way just click on the icon <i> save page </i> (it is next to the <i> cancel </i> icon)
. Hope this helps.
