If you use the forum Kunena they have a plugin called Kunena Discuss which I really like. It uses article comments to automatically create forum topics. This is prefect because it makes your forum look active and it gets rid of duplicate communications. Anyway since upgrading to Joomla 1.7 and Kunena 1.7 (which have the same version numbers just by chance) this great feature was a real pain to get working again.
Firstly, when a guest commented and clicked it did nothing but refresh the page and clear the comment form. Not a good experience for the guest. I also realised that the captcha was not showing. You really need that to stop the spam.
To date I have not solved this problem and therefore you cannot comment below ...
Checking the Kunena forums this is the best explanation I could find. There's an issue with caching in general on Joomla 1.7. The Joomla articles get cached after plugins get called and there's no way to turn the caching off. So for now Kunena Discuss on Joomla 1.7 is not available. Best to disable the plugin until its resolved.
CAPTCHA is not properly configured (public key is missing). Please contact site administrator!
