kenstone on "Redirect at login and "sufficient permissions" note"

I've been a WordPress user for years and have never had this problem. But it seems to be common in earlier years. (I've reviewed the threads mentioning "You do not have sufficient permissions to access this page")

Bottom line: I can't log into my WP account.

Different things happen in different browsers. To wit:

Chrome:

http://masterstrack.com/wp-login.php

Takes me here:

http://masterstrack.com/wp-admin/edit-comments.php?comment_status=moderated

Says: You do not have sufficient permissions to access this page.

Safari:

http://masterstrack.com/wp-login.php

Takes me here:

http://masterstrack.com/wp-login.php?redirect_to=http%3A%2F%2Fmasterstrack.com%2Fwp-admin%2Fprofile.php&reauth=1

Won’t let me in.

Firefox:

http://masterstrack.com/wp-login.php

Takes me here:

http://masterstrack.com/wp-admin/profile.php

Says: You do not have sufficient permissions to access this page.

Any advice?
