Change site's base url

I’ve just moved my WordPress blog from one domain to another. I’m having trouble changing the base url of the site, though. It used to be on test.domain.com, and now it’s just on domain.com. However, it’s still trying to access files (like stylesheets) from test.domain.com. Also, when I try to go to the admin panel, it redirects to test.domain.com and won’t stay on just domain.com.

I changed the “siteurl” and “home” values in the options table in the database, but that didn’t fix it. I figured maybe the changes wouldn’t take effect unless you save the config in the admin panel, but I’m not able to do that, seeing as how I can’t get in there without being redirected. All other posts I’ve seen about changing the base url say to do it in the admin panel. Is there a way for me to fix this issue? Is the base url set somewhere else that I just haven’t found?
