Hi, I followed the instructions on http://codex.wordpress.org/Moving_WordPress under 'Moving WordPress to a New Server' and 'If You Want Your Old Blog To Still Work'

So I made a copy of everything marked is as old, then changed the domain under the WP settings, made a new copy. And now put the first copy back but when I go to the login page I can reach it, but it's without the usual markup as first. It's all skinned out. After I login, worpress uses the new domain instead of the old domain which the old copy of wordpress used!! what went wrong?? thanks.
