I require guests to register at my homepage. When they do, I receive an email "A new user has registered on your website. This account must be approved before it is active and may login." When I click the link in the email to approve the user a browser window opens that reads "The webpage cannot be found" (see attached screenshot). When I hit the back button in the browser, it takes me to the page where I can approve. Any thoughts on why I'm getting the webpage not found?
