Redirect Loop on Home Page

Gents,

I have had this on two sites today. Still not fixed.

I cannot load the first page of the site. It just sits there. Admin panel works, and if I preview a post/page it works. Just not the home page.

On closer inspection, after setting the debug option in wp-config.php, I see that its in an endless loop of redirecting to the home page. If I load the first page and it gets ‘stuck’, I can edit out the redirect on line 897 of the pluggable.php and then it stops the loop.

Function wp_redirect:
header(“Location: $location”, true, $status);

Any ideas on why it would do that? And only on the first page??

Cheers, Ian

PS I am running IIS, PHP5, Windows Server 2003. Latest service packs, etc. I’ve tried removing all plugins. Only fix so far was to revert to an older version of WP.
