possible cause of the error of trac @425 and basic solution.
the error is chang prefix in tables, in all versions.
Is Basic, I am install new wordpress mu 1.3.2 with sub directories, first in wp-config-sample change wp_ prefix to asd89_ and install from domain.com correctly but the problem is what one user create account and when login from domain.com/newblog/wp-login.php nice all good , but login from domain.com/wp-login.php redirect to domain.com/wp-admin/profile.php, because change of prefix, solution: install with prefix wp_ and resolute problem, now login work in front page for users and admin, now redirect fine.
I deduce what... must modify something in the tables if install wpmu with another prefix.
