I had problems with links in the admin panel.
Some of the Query Vars returned twice.

The Normal Link should be:

But it appears as:

And that broke the link. the solution is to use


Instead of


I've changed all the $_SERVERREQUEST_URI? in functions.php and All works!

HTTP_SERVER_VARS is deprecated and won't be set if register_long_arrays is off. Any fix here needs to be done in wp_fix_server_vars(). Can you dump REQUEST_URI before and after wp_fix_server_vars() runs so that we can see if wp_fix_server_vars() is in error?

I would wager a guess and say that the person is still using PHP4, probably PHP4.2.

Actually I'm using PHP5.

echo '<br />' . $_SERVER['REQUEST_URI'];

Ok after some digging i found out that

echo $_SERVER['SERVER_SOFTWARE'];  // Results: Microsoft-IIS/6.5beta

The weired thing that i'm on Apache O_O
And that cause the IF statement to run the Fix for IIS

Anyway I've contact my web hosting company to figure that out...

OK i figure that out.
for security reasons $_SERVERREQUEST_URI?; output "IIS".
So I manually disable the part of the IIS Fix.

A workaround:
list($clean_url) = explode("?",$_SERVER["REQUEST_URI"]);

Use $clean_url in place of $_SERVER["REQUEST_URI"]

This works for the presented problem. There may be other issues arising from this bug, though.
