I'm having an issue with Firefox and logging in users.
I have the back end disabled for subscribers with a "!user_can('manage-options")" check, and the front end locked out with !is_user_logged_in(), which redirects to /wp-login.php for not logged in users.
The problem arises in Firefox (multiple versions) when accessing the front end (even as an admin, accessing from the back end via "view site" link) is that the user is automatically redirected to the login form. It's like firefox doesn't remember the login in the front end.
If I change the URL from the login from /wp-login.php to /wp-admin/ it will take me to the back end, which is telling me that the cookies are being written, but not working in the front end.
Could there be a redirect I am not aware of, which is triggering the redirect?
Thank you for your time and advise,
