رفع خطای 500 در قسمت مدیریت

با سلام

من بعضی موقع ها با خطای 500 در قسمت مدیریت جوملا ( فقط قسمت مدیریت ماژول ) روبرو میشم
سرچ هم کردم ، اون چیزی که دستگیرم شد این بود که در htaccess. متن Options +FollowSymLinks را جایگزین Options +SymLinksIfOwnerMatch کنم.
من این متن را در htaccess. پیدا نکردم در این فایل همش سه خط نوشته داره و این متن داخلش نیست. اما در فایل htaccess.txt این متن را پیداش کردم و تغییر دادم اما جواب نداد
موقعی که این خطا رخ میده ، مطالب سایت هم در وب نشون نمیده و با این خطا روبرو میشه :

این خطا از زمانی شروع شد که من پلاگین mooimageck را برای افکت دادن به عکس نصب کردم

ارور 500 معمولا زمانی پیش میاد که مشکلی از سمت سرور پیش آمده باشد و یا شما بخواهید مواردی را اجرا کنید که با قوانین (rules) های سرور مطابقت نداشته باشد.
به عنوان مثال در سرور بخاطر مشکل امنیتی مدتی قبل FollowSymLinks را غیر فعال کرده باشند و شما اگر از این مورد استفاده کنید با ارور 500 مواجه خواهید شد.

برای اطلاع دقیق از علت این ارور در سی پنل error logs را چک کنید. اگر از این قسمت مطلبی دستگیرتان نشد از پشتیبانی هاست بخواهید با بررسی لاگها مشکل شما را یادآور شوند
