The FB button shows on my site (not live, on localhost-my P.C.) but no response from clicking the FB button.
The author's demo also exhibits the same thing - doesn't open the light box.
This works perfectly on the demo site. it works perfectly on other sites that i have installed it on.
it also works perfect on mobile devices. im assuming you checked this on multiple computers?
As far as usability, at first I was a bit confused by how it worked with the layout and setting up of properties for forms, form elements etc.
I have seen a couple of the demonstration videos on the author's site and plan to return to watch others.
This gets a "good" rating (4 stars) due to my experience initially with the usability and "getting started" aspect, even though I figured it out in the end without any need for asking for support.
I tried to install the current version 1.7 in the stable Joomla 1.6 (January 2011 release) but it gives me PHP/database errors. No announcements (yet) on authors website either, about this.
Thanks for the comments. We have just released v1.8 beta of Freestyle Support which now supports Joomla 1.6. At the moment this is a beta version until we have had more feedback on the Joomla 1.6 site of thing to make sure they work ok.
