Page editor is blank while page is there

So few days ago I purchased the virtue theme, I made the page it is perfect and nice

I added and edited all the pages, but then when I wanted again to edit home page, if I got to the editor or click edit page it shows that the editor is completely empty, but the page it’s still there, the home page opens but if I wanna edit it, in the editor it is completely empty, any help ???
