I've completed the import from Blogger to WordPress following the instructions at:
Everything seems to work, all the posts and comments get transfered over, however there was one error message I kept getting over and over during the process which is as follows:
WordPress database error: [Unknown column 'user_nickname' in 'field list']
INSERT INTO wp_users ( user_login, user_pass, user_nickname, user_email, user_url, user_ip, user_domain, user_browser, user_registered, user_level, user_idmode ) VALUES ( 'Greg', 'password', 'Greg', 'firstname.lastname@example.org', '', '127.0.0.1', 'localhost', 'server', '1979-06-06 00:41:00', '1', 'nickname' )
: Registered user Greg
I would ignore it, but after doing the import, my WP runs extremely slow and am wondering if this error has caused part of the problem.
