I have users in the Site Owners group of a root site, trying to copy (or move) pages between Pages Libraries in two subwebs. The permissions of the subwebs are inherited from the parent, with no changes, so the Site Owners of the root are the Site Owners of the subwebs as well.
When a member of the owners group tries to move or copy a page, it fails. 12-Hive logs show an Access Denied error being thrown.
Is there any way to allow this to happen without giving these users Site Collection Admin access?
EDIT: This is via the Manage Site Content link in the Site Actions, on a Publishing Site. Copy/Paste or drag/drop between two explorer windows works correctly.
We had this problem on a couple of our sites as well. It turned out to be an issue with the page layouts associated with the content pages we were trying to move. Strangely enough, if the associated page layout had any draft versions in its version history then the move operation would fail with an access denied error. As soon as we deleted all draft versions on the page layout, the move operation would succeed.
I'm still not entirely sure why this worked - I'm hoping to find some time in the near future to do a little more investigation.
