copied site redirects to original after duplication

Hello,

I’ve duplicated my entire site and uploaded it for hosting under a different domain name. When I try to visit the new site’s homepage I get redirected back to the initial site’s home.

Note, I’ve copied/replaced all instances of the old site names/paths/etc to the equivalent of the new one’s. I’ve done this both for the files and the db entries (using interconnect/it). I’ve updated the wp-config.php of the new setup.

How do I track down what’s wrong?

Thank you
