Upfront editor will not save, "There has been an error saving your changes"

Hi I've been trying for days now to save my site in responsive mode. I must have tried saving over a hundred times at this point. "There has been an error saving your changes" is the error that comes up. I'm literally just hitting save nothing works. I emptied my cache and it made no difference. I'm using the theme with the couple on it. I'm not in a position where I can change themes and I need to get this responsive edits saved or I'm in big trouble. Please help, I paid a good amount of money for this editor and I would hate for it to be the reason my site dosnt go public when its suppose to.
