Account verification

Hi,

I have instaled Ultimate Member on my WP page. I have also created registration forum and enabled email aproval of new members. However, as a new user is registered, no email with verification link is sent and as I click on the link of activate your account button in Ultimate user / setting / email / account activation email, i get the following text on the site: This page doesn’t seem to exist.
It looks like the link pointing here was faulty. Maybe try searching?

So I have 2 problems: how to get email with confirmation link to be sent and new users not being automaticaly aproved (I have eneabled the require email activation option under ultimate member / user roles / suscriber (and also at customer)) and the other problem: how to get the activation link in the mail (when we solve problem 1 ?? ), to work and not get the message written in the upper text.

Thank you
