OK, this is embarrassing, but it turned out that when the import script brought over our entries from Typepad, all of the users were preserved but their role was set to “subscriber”. Thus, Admin was the only author left. And I didn’t notice that at first. Stupidity FTW!
Thanks for the help.
I’m sorry, I should have noted in my original post that I tried that one already too. Thanks for the idea though.
Other ideas?
