This indeed does not allow anonymous users to edit.
But, it also
prevents registered users from editing and saving. When they hit the
"Save page" button, they get the message, "Remember that this is only a
preview, and has not yet been saved!" as if they had hit the "Show
preview."
And, in fact, when I take $wgGroupPermissions settings out, only
anonymous users can edit and logged in users see the same behavior as
above. Arrgh!
Sounds like you have a problem with session data; this is unrelated to
the group permissions, and will cause edits and other actions by
logged-in users to fail due to the failure of a security check to
protect against hijacked sessions.
Make sure that PHP's sessions are configured correctly to save to a path
that actually exists. If you're on Windows, the default is almost always
wrong. If you're on a shared server farm like Sourceforge, you may need
to customize the path to a shared network location instead of the local
hard drive of each server.
