Just moved my installation from a subdirectory to the site root according to instructions for moving to another location on server. Now, the site will display, but fonts are different and I can no longer login to admin. Site URL and Home are set properly in DB. Manually entering mysite.com/wp-admin/ returns a blank page. If I enter mysite.com/wp-login.php I get the login page but, when I submit the login, it returns a blank page. Help!
