Remove Comment box on LIKE Button

You can't. That's a built-in feature of the Like button. When a user clicks Like and doesn't leave a comment, the Like has less prominence (not shown to as many of their friends). When they leave a comment and choose to post it to their wall, Facebook knows the user really, really Like's the page and gives that action more weight.

Unfortunately though, there's no way to simply hide that comment box.

Hope that explains,

Glad to hear that helped explain. As always, should you need anything else, just let us know.

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
