Yesterday, I updated my WPdiscuz after not having updated in a long time.

I immediately noticed that I could not comment, then realized other users on my high-traffic site could not comment either. Any attempt to comment generated an "INVALID NONCE" message.

I cleared all my caches--to no avail.

I then rolled back through the last seven versions of WPDiscuz -- nothing helped, still INVALID NONCE whenever I or a user tries to post a comment.

Any help here would be greatly appreciated, as my comment section helps drive traffic to my website.

Thank you.
