Remove Mirror Process

I had a domain mirror ( setup to mirror a fully hosted domain ( so I could setup the site before I changed the nameservers. Once everything was setup I changed the nameservers to the dreamhost nameservers and deactivated the mirror. Once the nameservers updated and went to it gave me the error id: “bad_httpd_conf” page. I then deleted the mirror hoping that would help but it didn’t.

My question is what is the proper way to remove a mirror so that once your nameservers update it directs you to and no longer I deactivated the mirror first and then just deleted it. That’s what gave me the error. Thanks!
