Editor not working

Hi

I am using WordPress 4.2.1 running Contango theme.
I was using the Single page theme had copied my Wording from Microsoft word, adjusted some formatting then tried to add images, I added four 250×210 images in a row, then tried to preview.when I came back to The edit page the page was blank, however where I believe there were spelling errors there were wavy lines on the editor-just like the incorrect spelling underlines.

All the menu buttons were not displaying, now this had happened on another site so I deleted the Akismet plugin and it was ll ok after that.
however for this unpublished site I had to delete all the Plug ins and went back to the contango theme and still no Joy.

Ive now deleted all pages and posts with the result that still no buttons show when I try to start a new page, the only button that shows is the add media. however the Media on the main Menu, when clicked, only shows add media even though there were images there. I could however see them via the page view. I have since deleted those in case they were the problem,

The whole admin site is not working, and I am now down to no plug ins no pages and no images. I just have general setting set.
