I have upgraded from 2.3 to 2.6.2
Just unzipped the whole thing in place.
Probably should have read the instructions carefully and do something else instead.
I want to login to the dashboard as admin
I don't get a username/password error
Username and password are correct but I get back to the login form and not to the dashboard.
When visiting the blog, I get the "edit" link for each post, which indicates that I am logged in correctly.
I have cleared all cookies related to this blog.
The cache dir is empty.
I have googled and looked in the wordpress forums for solutions but found none.
Any suggestions ?
