Wp 2.8.2 (I Think)
When I login in at my /wp-login.php the login page leaves me at /wp-login.php with a blank screen.
When I type in /wp-admin I get a blank screen again.
So I know the files wp-login.php and wp-admin.php are there because I get a blank screen and because I looked.
My provider migrated to a new system last week, it took them about 8 days.
The provider’s wordpress’s login works fine.
My WordPress MU with about eight blogs works great also
