Hi

 

I have been using the EditorWysiwyhModeCSS property. All was fine until i changed it to use a dynamic url. e.g. 

 

However i get the error

 

'~/site/previewpage.ashx?id=48577' is not a valid virtual path.

 

I cannot see anything wrong with the filename, am i doing something incorrect?

I have just downloaded the latest version 6.3.

 

cheers
