Has anybody ever seen this error message before when trying to export a web
part:
A Web Part or Web Form Control on this Web Part Page cannot be displayed or
imported because it is not registered on this site as safe.
I'm just trying to export the out of the box web part called Page Viewer from
one area to another area in the portal. I understand that you have to do some
stuff in the webconfig file when you have customized web part or make it safe or
something like that. But my question here is, why am I getting this error
message for a web part that is out of the box?
