Hi, I'm running 2.7, having upgraded a week ago. Today I tried to open a series of sub pages, six in all, from links on my main page but I get a blank page and the message, "You do not have permission to preview drafts."
These sub pages are not drafts. They have all been published in the past and are inaccessible as from today. I tested my site as a visitor, logging out of admin, and still the pages appeared as blanks. The title and comment boxes sections were visible at the top and tail of each page, but all the content that you'd see in the edit box was missing.
I can still open the subpages in the dashboard editor, in visual and html view, and the material is there. However, they cannot be previewed or visited.
Could it be that when I originally linked the pages, I linked the main page to the preview URLs? I can't see that being a problem in that my sub pages only became blank today. Although my content exists in edit view, I don't want to cut and paste it on to new pages and lose all my existing search links.
The one thing I did today was load the Feedburner plugin for WordPress, which I've since disabled and can't imagine that this is the problem.
I wondered if there might be a hitch with page autosaves from the past replacing my saved material with a big nothing. Is the autosave function writing blank space over actual pages that still open but only in edit view? When I try to preview from the dashboard page/post editor, I also get a page devoid of content
