Redirect Bug after FTP Transfer

Hi,

so I have a weird error on my site http://www.thrivemusic.com

when I try to access my wp-admin, it redirects me to http://beta2.thrivemusic.com

beta2.thrivemusic.com is the beta site that I transferred the files from via FTP but after the transfer, I started getting these improper redirects…

How do I fix?

Thanks in advance
