I have a publishing site, and we have been trying to customize the views a little bit. We have added a CEWP to the page. I keep getting this error though, and I'm not sure where to look.
"Unable to add selected web part(s). The file is not checked out. You must first check out this document before making changes."
Since it is a view the page cannot be checked in or out.
Default master pages are still in play, no modifications there.
