Access Denied on Site with Publishing Turned on

Sometimes, 'Content Editor' type users will receive an Access Denied message, but the message will be cryptic in that it will also state that a list cannot be found.

Some things to check:

1. Ensure all of the master pages and page layouts are published major version, checked in and approved. From the Top Level Site, Site Settings --> View All Site Settings --> Master pages and page layouts, (http://[sitecollection]/_catalogs/masterpage/)
2. Ensure all of the Style Library (http://[sitecollection]/Style Library/) files are published major version, checked in and approved. From the Top Level Site, Site Settings --> View All Site Settings --> Master pages and page layouts
3. Ensure all of the elements on that page are published major version, checked in and approved.
4. Ensure the Master Page document library has at least RESTRICTED READ access for all users.
5. Ensure the Style Library document library has at least RESTRICTED READ access for all users.

This should resolve the cryptic error messages.
