Cannot edit my site in OneTone

I have not been using my site for over a year now. I went back in today to update and edit it but now it is controlled by “OneTone” and I cannot seem to be able to make any changes. In particular I am wanting to change how the video on the home page is displayed but cannot seem to locate at all where I would begin to make that change. can anyone assist?
