Incorrect Blog Root

The old versions of the home and site url are likely in the database somewhere.

Add two lines to your config.php file to override them as needed:

define('WP_HOME',     'http://example.com');
define('WP_SITEURL',  'http://example.com');

If you visit Settings / General and save the settings, they should get stored to their new value in the database. You should then be able to remove them. (Alternatively, you can skip that part and just keep them around: they won’t hurt.)
