No one can register to my site, because there is no new user confirmation email being sent out. Whenever anyone registers at my site, http://www.waarba.com, they get a page that says, your account is set-up pending your response to the confirmation email. But the email never gets sent out!
I have been looking all over the back end for an email setting... but can't locate a setting. I am using multi-site, pro-sites, with ultimate facebook.
