Drupal 7 with Seven as admin theme and ck-editor for text editor.

Ck editor works fine for creating a new node.But when we edit the existing content the text area shows the whole dash board itself! I can't edit the content.

I am attaching the screen shot of the actual display.

Clear your Drupal caches and your browser cache. That might fix it.

If that does not fix the problem turn off javascript aggregation unnder Config > Performance annd look for a javascript error, perhaps using a tool like Console in Firebug.
