I was messing around in the admin panel , trying to change the header link address from my http://www.domainname.com/blog to the root to http://www.mydomainname.com
anyway I changed the address in the first box of the admin links panel to
http://www.mydomainname.com and saved it. now it doesn't load my theme or even let me login. I get a 404 error.
I'm in some serious crap if I can't fix this quick. please tell me how to get to the login, or which file to replace it with (I have an outdated copy of the blog I think).
Thanks!!!
