CMS Article comments
 

I keep getting this message whejn I try to reply to a comment on an article:

Quote:

It doesn't happen on every article, only on some. I suspect it's because I've written it, published it and then edited it a numnber of times as this is all I can see that is different about this article. I'm also unable to add new comments to this article (as well as reply to existing comments), but I get no error message when I write a new comment, i just submit it and it takes me back to the article and the comment isn't there.

Has this come up before? If not I'll file a bug but I couoldn't find anything in a search.
