Issues with domain/admin panel

The website of the newspaper for which I’m the online editor, wildcat.arizona.edu, migrated from http://www.dailywildcat.com long ago, but previous online editors decided (out of beligerence or ignorance) to keep our blogs page at blogs.dailywildcat.com. I finally got the administrator’s login for WordPress from our editor in chief, and so I logged in today.

I created a page on our site to try to re-map the blogs, making wildcat.arizona.edu/blogs2, then I changed the setting in the WP admin panel to reflect this change, and now the whole thing’s a mess. I can’t change it back to blogs.dailywildcat.com, because I can’t even login anymore. Help?
