Ok, I really need help. reCAPTCHA is most difficult to install and Joomla reCAPTCHA Integration Plugin, at least when integrated in Joomla Comments, does not seem to make things easier. Placing the code (in exclusion syntax) only makes reCAPTCHA appear on the component. The component's SEND button does not work with reCAPTCHA. It seems, as reCAPTCHA instructions say, some script have to be changed in some file that handles the send command/function. This is really the obscure part. In the case of the Joomla reCAPTCHA Integration Plugin,
(1) WHICH FILE (name and path) should be changed
(2) with WHAT CODE?
Your reply will be much appreciated. Thanks.
