I just noticed that the Quick Reply comment box is not showing on one of my sites with 6.02 installed. I am logged in in the attached photo so you can see what my members see. Any ideas?
My initial response would be based on prior issues like this to disable any plugins you have installed that would affect the posting interface and then you should be fine. You would have to contact the hack author of any plugin your running on how to make it compatible with the product.
Correct your forum box would show up fine as you have a hack installed that works on the forum as hooks are done to work for that but the issue is when you install a hook unless say its globally defined and the hack is written to show other places then where it was written it will break a comments box showing somewhere else which is what you have.
