Symptoms: You are seeing a background image when editing content with the Telerik Editor in DNN and don't want this there.

Solution: There is a CSS file that allows you to change this behavior by the editor, which inherits the background image from your page  It is located under Providers\HtmlEditorProviders\Telerik\ EditorOverride.css under your DNN instance, to get rid of the backround image.

Please backup this file before trying this solution!

Add this to the next empty line in the file:

body
{
background-image: none;
}

This will get rid of the background image when you're editing the content.
