Assistance with WPScan error

I know that WordPress sites get attacked all the time, so I'm working on hardening the security on my site using WPScan. The problem I'm running into though is that when I run a brute force attack on my site, I'm getting the following error: "ERROR: We received an unknown response for <whatever password it was trying>" I think this might be because the WPScan looks for [login to view URL], in which case my theme redirects you to http://domain/login/ I've already tried using the --follow-redirection switch with no change in the outcome though. I also found this, which seems to be the same issue: [login to view URL] But to be honest, I don't understand the one guy's response about the login_url used being from the WpUser model and not from the WpTarget. So I really just need someone to help me get over this hump (help me understand why I'm getting the error message) so that I can continue to do my own penetration testing. I'm guessing this will be fairly easy for those of you who have done penetration testing on you own sites. I prefer to keep my domain private, but if you're awarded the project, I'll be happy to provide a copy of the theme so that you can do your own testing.
