This code isn't working on my server - WHY?

[Hellcat]

Hi!

I have this snippet of code:

PHP Code:

  $vbulletin->input->clean_array_gpc('p', array( "countdownuserfield" => TYPE_STR,
                                                 "cdsettings"         => TYPE_ARRAY ));

  $cdsettings     = $vbulletin->GPC["cdsettings"];
  $cdprofilefield = $vbulletin->GPC["countdownuserfield"]; 


It runns fine on my local test vB, on a 1:1 copy of my live board made on my laptop and for many other people that installed my hack using this code.

BUT:
On my own live server this code does: NOTHING!
The two var's are supposed to get filled with the contents of the GPC stuff, but on my live server they are not....

WHY?
Anyone got a clue?

PHP version on my server is 4.3.1-52, my local testsetup runns 4.4.0

If it's a problem with the PHP version?
Unfortunately I am not able to upgrade the PHP on my server ATM.... Is there a workaround?

I also tried turning SaveMode off - didn't help either.
