Access Denied

1. I installed drupal 7.26 using tedx profile 7.x.1.1
2. Got admin access to the site.... all seemed OK.
3. Logged out...and got access denied error.

checked for

node_access VALUES (0, 0, 'all', 1, 0, 0);
users (uid, name, mail) VALUES ('0', '', '');
users_roles (uid, rid) VALUES (0, 1);

www.sdi.org.in

Is there any mismatch between latest modules and profile?
Something to do with authorize.php.... or some permissions settings?
