The issue comes from the ACF plugin. You've hidden the ACF plugin fields via some custom code, but those fields are required. You'll need to contact the ACF plugin support and ask them to set those fields non-required. 

My issues is that new forum members are unable to register.

Once they put in their account info the register button does nothing.

I need to be able to have new members register for my forum on my site.

Any help would be appreciated.
