I am having the same problem. I thought that my plugin to get rid of the admin bar was the cause, but after renaming the plugin file I am still unable to get the admin bar. Trying to get to seedministriesinhaiti.org, seedministriesinhaiti.org/wp-admin and seedministriesinhaiti.org/seed/wp-admin all bring me to the main page, and I have no way to get to the dashboard/admin bar.
