After spending hours trying to figure out why I was locked out of my site today with my admin account (could not login, even after password reset through phpmyadmin, and password reset through wordpress) - multiple 20 min lockets, I started deleting other plugins, and was about to start deleting themes, when I cam across post from a search
( http://wordpress.org/support/topic/plugin-theme-my-login-too-many-login-attempts )
and found that indeed, after deleting theme my login plugin, I was able to not longer be locked out and log in as admin.
Now I have another problem, with my wordpress multisite / buddypress, the login button at the top left admin directs to a page like:
www mysite wp install/login/?redirect_to=http%3A%2F%2Fwww .mysite wp install .com%2Fsubdir
and that page only shows:
so, I am not sure how to fix this.
