Yes, I’m afraid you’re experiencing the same problem I did. It initially seems to work, but the privacy settings in fact fail and RSS feeds no longer work. I found that I just couldn’t get the functionality I needed in 2.5, whereas it worked just fine with earlier versions.
I appreciate your checking on this. I wish the original author would update the plug-in, since it wasn’t immensely helpful to me. I tried contacting the author, but never got a reply.
