URGENT! Url change, can't log in!

did you also change the wp-config.php file to reflect the changes to database?

or delete the .htaccess files so they aren’t pointing in funny permalink places.

what do you mean by “can’t log in” do you mean the login page isn’t at the address you expect it to be or do you mean you are receiving login errors?

Actually it looks as though the new URL contains a default bluehost index page. You will need to delete that as well. probably named “home.php” or “index.html” or something
