Ultimate facebook plugin not auto-posting to my wall or displaying comments

I just downloaded the latest version today, installed it, and everything seems to work fine except for those two problems.

Problem #1

I made sure the “Use Facebook for comments” is checked. “Override WordPress discussion settings” is also checked.

But it’s still the WordPress comment system that appears!

Problem #2

Plugin is not auto-posting to my wall.

I made sure that “Allow autoposting new posts to Facebook” is checked, and the apps has post to wall access.

“HenryPena.Info may post status messages, notes, photos, and videos to my Wall”

and the “Autopost Post to Wall” is selected w/ “Me” in the user box.

But when I post on my blog, it doesn’t autopost to my wall.

Please help!
