Login sends me back to old domain

Hi,
I used your plugin multiple times, and every time it went great. But now I moved a new website for a client from a subdomain (http://staging.stookjerijk.nl) to the main domain (http://stookjerijk.nl). And when I moved the old website to the subdomain all went well untill the link came up to save the permalinks. When I clicked on the link I had to login. Every time I try to login (http://staging.stookjerijk.nl/wp-login.php)I get redirected to the main domain (the new website) and the login doesn’t work. So I can’t get into the admin on the subdomain to save the perma-links. The homepage works but al the links end in 404 pages on the main domain.

Any way of fixing this?
Thanks
