ISSUE SUMMARY:
When a user tries to register on the site the process will not move past the first page where the name, username, email and password are entered. The site uses JFBConnect and registrations made using the 'Facebook' button work and progress to completion. This process had worked prior to an update of JomSocial and JFBConnect but I can't identify which may be causing the problem.

STEPS TO REPLICATE:
1Choose 'Register Now' or registration option from the 'Login' menu item.
2click on the 'Next' button at the bottom of the form.

Hi,

I cannot access your administrator page, got internal server error.
I have a look the issue at your frontend. please turn off any script optimizer from site template configuration or any plugins.
script optimizer not works for jomsocial, because jomsocial side has been optimized by using Grunt.

Regards
