Is it just my site, or is this the normal behavior

When you register as a new user, an email is sent to you to confirm.  OK here.

When you open the email and click the link, you get two messages!  One is ok; it says that Your account needs to be validated by the site admin before you can use it.   BUT, another popup, at the center of the screen, titled "Bad Request" and has the word "error" on it, indicates the same,,,,  (hat Your account needs to be validated by the site admin before you can use it.). 

That is horrible experience.  The bad request should not display!!!   

How can I resolve this?   

Thanks, 

David S.
