• Strict Standards: date() [function.date]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Tehran' for 'IRST/3.0/no DST' instead in/home/sabadefile/domains/sabadefile.co/public_html/admin/include/jdf.php on line 48

سلام... تو این نسخه‌ای از PHP که شما استفاده میکنی باید منطقه زمانی (Time Zone) را مشخص کرده باشی، خیلی راحته ابتدای فایل PHP این خط رو اضافه کن.

date_default_timezone_set("Asia/Tehran"); 

تو خط بالا منطقه زمانی رو تهران در نظر گرفتیم.
لیست کامل Time Zoneها :

در ضمن بهتره نمایش خطاها رو به کاربر غیرفعال کنی:

ini_set("display_errors", "Off");
