Webalizer Fail When Changing IP

On both of my Virtualmin servers I changed the IP of a site. Both gave out this error,

Webalizer reporting failed! : Undefined subroutine &htaccess_htpasswd::encrypt_password called at /usr/share/webmin/virtual-server/feature-webalizer.pl line 508.

Is Webalizer no longer going to report?

Also, my site doesn't even show up now. It shows a random site on my server. I think that's because my computer is still accessing the old IP though, and no vhost is setup with the same name as my site for that IP (obviously) so it's going to the default.
