Hi Balan,

I'm sorry but Visforms needs Joomla! 3.2.0 or higher.
When I started to develop a Visforms version for Joomla! 3 this was already the current Version. So it didn't make sense to develop for a Jooma! version which were still outdated. Actually I didn't test on Joomla! 3.1 so I didn't know whether or not it would work.

I mentioned these system requirements in the download section for Visforms 3.0.0 but maybe I have not made it that clear in the description for the latest releases (3.1.0/3.1.1)

Regards,
Aicha
