Plugins stopped working

I originally had Spam Karma running and working perfectly on my site. I changed domains and hosts yesterday. Site is up and running however Spam Karma is all of the sudden killing every single comment that is posted. I checked the settings and all is fine. WP 1.5 is a fresh install. I tried installing Spaminator and it does the same thing… kills every single comment.

I can only guess that it has something to do with something on the new server? Is there anything particular that might cause this to happen? Is it possible that everything just isn’t propagated yet and that is why things are behaving strangely? I am so confused over this one… not to mention frustrated. LOL

Thanks!!
