UserPro issues in Wordpress

Me

Hi I need you expertise,

I've recently added a forum on my site and I bought UserPro, a community WP plugin. The forum is all set up but the problem is that you cant register new users or log in.




We did get a reply from UserPro. They first suggested turning off all other plugins and/or switch to the default theme to see if it was still non working. But unfortunately disabling the plugins didn't work. :/




We're now stranded..Can u fix this? We need this to be fixed ASAP!
