تاریخ جلالی ips4 افزونه تاریخ جلالی برای سیستم انجمن ساز ips4 1.0.0

سلام جناب محمدیان

وقتی این مد رو نصب کردم خطای زیر پیش میاد
Fatal error: Cannot redeclare class Jdatetime in /home/passion1/public_html/forum/system/3rd_party/Jdatetime/Jdatetime.php on line 43
ممنون میشم راهنمایی بفرمایید
با تشکر و سپاس...

class Jdatetime
{

    /**
     * Defaults
     */
    private $jalali = true; //Use Jalali Date, If set to false, falls back to gregorian
    private $convert = true; //Convert numbers to Farsi characters in utf-8
    private $timezone = null; //Timezone String e.g Asia/Tehran, Default is GMT
    private $temp = array();

برای بنده هم بعد از نصب فایل IRjalali.xml   این خطا رخ میدهد.
