Access Denied Error while creating new article page in SharePoint MOSS 2007

A user with Full Control permission on the top site could not create an article page. The error message was Access Denied.  I tried different ways to resolve this issue, include put her Full Control permission directly on the top site and Page library, but still had the same issue. Then I assign Full Control, Approve and Contribute and all permission levels to her, I got the following error:

List does not exist

The page you selected contains a list that does not exist. 
It may have been deleted by another user.

But this user can do everything else except the Create Page from the Site Action drop down. From the URL, you can see the Create Page is using /_layouts/CreatePage.aspx file which I believe is using publishing template

Resolutions Steps:

•  Go to Site Setting –> Modify All Site Settings from the Site Action drop down.
•  Select Master pages and Page layoutsfrom the Galleries section.
• From the Master Page Gallery document library, select Document Library Settings from the Setting drop down.
• And select Permissions for this document library option, and double check the permission setting. To be simplified, just inherit all permissions from the parent site. Then the user with full control permission will be able to create article page there.

          There you go!!!
