same problem here! there’s another thread with the same issue, posted a few months ago http://ww.wp.xz.cn/support/topic/wp-admin-not-found-site-works-fine-cant-edit?replies=9
i have re-uploaded my wp-admin directory, cleared my cache, and even tried the suggestion here http://www.kinocreative.co.uk/hints-and-tips/wordpress-cant-login-to-wp-admin/ (this might work for some of you) but i still can’t log in to wp-admin of my site. i have also sent a support ticket to my webhost (pacifichost) to see if the problem could be from that side. anyway i hope someone posts a solution soon.
