Comments submitting like a search query

RE: http://www.masey.com.au

I have no idea why all of a sudden when you try to add a comment to any of my entries you get the error message:

“Sorry, no posts matched your criteria.”

It’s almost like the submit button on the comments are treating them like a search query or something? Has anyone else encountered this?

I use Spam Karma 2… would this have anything to do with it? I have tried commenting with the Spam Karma 2 plugin disabled… didn’t make any difference.

Please Help!!!!
