array_key_exists ERROR updating to GS 3.2.1

[D.O.]

Hi again shawn,
then I waited and I tried even with the new GS version 3.2.3 but nothing to do, it shows the same error...

PHP Code:

Warning: array_key_exists() [(function.array-key-exists)]:
The second argument should be either an array or an object in
D:\Inetpub\webs\my_site\admin\inc\caching_functions.php on line 52 


at these lines....

PHP Code:

<?php getPageField($pagina,'pubDate'); ?>
<?php getPageField($pagina,'title'); ?>
<?php getPageField($pagina,'metad'); ?>

but weirdly not on this line...

PHP Code:

<?php getPageField($pagina,'content'); ?>

Instead wirg gs version 3.2.0 I have no problem.
Any help???
