The System Cannot Find the File Specified

When you try to edit my content editor web part in SharePoint 2010 environment, you may face the issue"The system cannot find the file specified. (Exception from HRESULT: 0x80070002").
 
This is due to the fact that publishing feature is not activated at the site and site collection level.
  1. harePoint Server Publishing Infrastructure feature found at Site Collection Administration – Site Collection Features.
  2. SharePoint Server Publishing feature at Site Administration- Site features.
