I created a subdomain (dev.mysite.com) and I duplicated my live site into this subdomain. However, when I go to dev.mysite.com, it loads mysite.com/dev instead.
I changed siteurl and home in wp_options to dev.mysite.com, removed the entire .htaccess, deleted W3 Total Cache, and it still does it.
When I just put a test index.html file, the subdomain loads correctly. It's only after I add the Wordpress files that it does this.
Am I missing something? What would cause this?
