Iam getting the Error : You are not authorized to access this page. when i try to load the admin page since iam also unable to see the login page, please help me solving this. Can see the screen shot aswell.

Login page is working well:

http://currentconservation.org/user

If you can't see it try clearing cookies for that domain. Or did you maybe added some records in your machine host file so normal DNS server is not used? Try opening login page from another computer. Or try visiting

http://currentconservation.org/user/logout

Maybe you are already logged in with some strange user account...
