This started happening today for some unknown reason.

When I am in the admin section, it starts out as SSL but when I choose a different menu, it goes to a non SSL connection.

I did set the admin SSL information as shown below and it has been working in SSL only for about a week now. The only thing I changed since it started doing this was commenting out a line in the fedex shipping module so that all shipping fedex shipping options show along with free shipping. I don't THINK it started doing that after that change, just stating that as the only change done since this started to occur.

This was done:

"NOTE: As of v1.3.x, the Admin area can only secure the "login" page via SSL unless you set the HTTP_SERVER in your "admin/includes/configure.php" to an SSL URL, in which case the entire admin area will be treated as SSL rather than only selected relevant pages. This will be changing during the admin-rewrite phase scheduled for completion sometime after Zen Cart v2.0 is released."
