We recently upgraded to PHP 5.3.10 and now I am seeing this error in the log that I haven't seen before: PHP Warning: strip_tags() expects parameter 1 to be string, array given in /adminfolder/includes/init_includes/init_general_funcs.php on line 54

Line 54 of that file reads:
Code:
$_GET[$key] = strip_tags($value);
I will appreciate insight into how to solve this problem. Thanks!

Currently using Zen 1.3.9h and PHP 5.3.10
