Page is not visible using upfront editor


Some script got bad and then my page is lost and i am not able to reverse the change now.

Whenever i try to edit my page with upfront, the editor comes up and page is lost. Snapshot attached. I know the problem is with google maps plugin, i deleted the plugin also but the problem is still there.

Also, i am already facing this lost page/lost editor problem in my home page, which is still not resolved.

The only option you guys give is reset the theme.

But do we really have any other options to correct a error except making the whole website again just due to one hiccup in the theme.

It seems like i made a few websites in this theme and now i should remake them without using this theme


Early responses and feasible resolutions will be appreciated.
