Skandasoft, Browser-Plus plugin not working since today


Hi, i’m new to Atom, and i’ve quickly found Browser-Plus plugin wich is a very cool plugin for me as i’m only doing CSS.
But since today when i CTRL+ALT+O, the browser opens but shows my website not up to date. F12 debugger even doesn’t shows my changes (that are actually in my css file).
And Chrome does show my changes.
Have i down something wrong?
Can you help me make it work again?
Thanks !
PS : i’m not a developper just a webdesigner


NOTE : Enabling “Disable cache” in Dev-Tool (F12) in the network tab seems to have resolve the issue.
That means the cache was taking the lead? Is there shortcut to empty cache in browser plus?
