I was having an issue with our new user registration in Jomsocial. When a new user attempts to register, the "Next" button on step 1 of registration does not go to step 2. Button works as if there is an error in data entry, Jomsocial picks it up and indicates the error. Put the next button won't go to step 2. I am using the Jomsocial redirect plugin for user registration so all registrations go through Jomsocial.

Steps to produce issue on my site (603sports dot com)
If user clicks the "Newsletter" radio button and fills in data, registration will go to step 2.
If user does not click the "Newsletter" radio button, the next button does not go to step 2.
If I disable Community - CMC Registration plugin, registration goes to step 2. (I have disabled CMC plugin for now but would love to turn it back on ASAP)

Thanks for any help with this. Seemed to start as I look back when Jomsocial went to 3.1. Before that there was no issue. I've tried turning off every extension/plugin, reverted back to Joomla default template in order to confirm that it is not a Javascript or template error of some sort and problem still existed on my site. If I disable the extension all is good with user registration.

Joomla 2.5.18
Jomsocial 3.1.0.4
CMC 1.4
