Using 2.6.5 I am having two issues. First, when going to /wp-admin I get redirected to wp-login.php?redirect_to=http%3A%2F%2Fmyblogurl.com%2Fwp-admin%2F
It will then say my password is wrong, even if I reset it or change it via phpmyadmin. If I go to /wp-admin from the weird url above, it will log me in.
The 2nd problem revolves around one post: http://tinyurl.com/574p6o
The post loads until comments section should, and then stops loading. I talked to the disqus folks and they don't think it is a problem on their end (it only doesn't load on one post).
