I'm having trouble getting past the nonce verification in 3.1.2. We are using WP Super Cache, so I'm not sure if that is adding to the problem or not. In any case, messages end up getting flagged as spam and not sent when I leave the constant WPCF7_VERIFY_NONCE true. As long as the constant is false, the same exact message sends without any trouble.
Any help would be greatly appreciated.
