i did a fresh install of 3.1.2 and a new database through Godaddy hosting. i can't create any posts or pages without getting this error:
You are not allowed to edit this post.
i also tried to trash some existing posts and got similar errors about how i can't move to trash.
i'm the only user set up and i'm an administrator - it shows me logged in as well. i also disabled all plugins and reverted to the base theme - same story.
the only thing i really did that was extraordinary is import some posts from an older version of the blog and map the users to the one user account.
if anyone can help i'd appreciate it - pulling my hair out over here.
