Thread:Project:Support desk/Mass disappearance of pages in mediawiki upgrade/reply (2)

Thanks. The site functions as a kind American lit anthology authored by students in successive classes. So, for instance, the Texts page should have links to about 20 to 25 pages with texts (The Waste Land,short stories, etc.). I can't explain why just the just the Whitman - "Song of Myself" page remains. In addition, there were author pages (Twain, Whitman, Chopin, etc.). The Contexts link should, again, contain links to various historical, thematic, etc., pages that the students authored. All of these pages - -and work - -have disappeared. I'm stymied.
