Hi Leonid, 

Thank you for the reply, I am looking for a solution to 2 problems with this:

1. I have Ad Code that is appearing on the "Error Pages" that essentially have no content. I would like to prevent Ads from displaying on these pages.
2. The Current Error pages act like a "Stop" sign, offering no path forward to other content or parts of the site. I would like to give the user options to choose a path forward. 

Is there any way for me to Edit the "Error" pages at a source level?
