Getting Client CurrentUser in Feeds

[HancoEuropa]

Sorry to bother, but I must be missing something fundamental here.

I'm a noob at feeds (clearly).

productsinfo.php is working fine, producing results perfectly in the Wordpress header.

I'm doing a "userstatus.php", but I can't seem to get ahold of the CurrentUser

Tried:

(See screenshot 1, cloudflare on this board isn't letting me paste php code ...)

Also tried the old fashioned way:

(See screenshot 2 please)

Neither work -- both return "Logged Out".

For voodoo, I included script in the wordpress head:

(screenshot 3)

What gives? Why can't I get the SESSION or the CurrentUser using a feed in a wordpress page?

Perversely, even when the clientarea is showing (see attached), that feed will throw up "Logged out" :)))

Clearly I'm missing something quite obvious!

Thanks,

David
