New Threaded Comments Plugin

I’m commenting here because I couldn’t comment on your blog for some reason – it kept timing out.
I’ve just installed (and activated!) the plugin and replaced my comments files with yours, and I get the same error message as one of the recent commenters on your blog (“Warning: Invalid argument supplied for foreach() in /homepages/20/d88608368/htdocs/kambiz/anthropology/wp-comments.php on line 88”, except with my URL in the middle!). Any suggestions would be most gratefully received, as I love the look of the threaded comments.

I get the same error on my blog as well – I just spent over an hour banging my head on my desk over it and I can’t solve it.
