I tried to upgrade my wordpress from 2.5 to 2.6.2, I followed every steps. But the problem is I can't login. I read on many posts before, that suggest delete my .htaccess files, but still didn't solve the problem. I even try to re-install my wordpress, and re-import my sql database, and it didn't work too.
my blog is http://raccoonnest.com/
does anybody know how to solve it ?
