[_ck_]

I have a crazy idea to try to “fake out” bbPress and make it think request_uri actually exists on the IIS server so it doesn’t try to (incorrectly) calculate it itself.

Try saving and installing this as a plugin with a leading underscore, ie. _IIS-fix.php

<?php

/*

Plugin Name: IIS request_uri fix

*/

if (isset($_SERVER['HTTP_REQUEST_URI'])){

$_SERVER['REQUEST_URI'] = $_SERVER['HTTP_REQUEST_URI'];

}

else{

if(isset($_SERVER['SCRIPT_NAME']))

$_SERVER['HTTP_REQUEST_URI'] = $_SERVER['SCRIPT_NAME'];

else

$_SERVER['HTTP_REQUEST_URI'] = $_SERVER['PHP_SELF'];

if($_SERVER['QUERY_STRING']){

$_SERVER['HTTP_REQUEST_URI'] .=  '?' . $_SERVER['QUERY_STRING'];

}

$_SERVER['REQUEST_URI'] = $_SERVER['HTTP_REQUEST_URI'];

}

?>

no activation required, should auto-activate – just delete if it causes problems
