Me too. When I try (or anyone else tries) to enter the post’s password, we get sent back to the same screen with the “enter your password” box. I can’t view the protected entry or its comments.
Ah! Somebody else had this problem, too. Now for my question: how can this method be used with teaser text? That is, I want to use extended entries, but the fix given above sounds like it’s just going to print the whole entry all the time.
