سلام بعد از نصب و اجرای مراحل ionCube کار نمیکنه

Site error: the file /home/shweb/domains/sharifweb.com/public_html/index.php requires the ionCube PHP Loader ioncube_loader_lin_5.5.so to be installed by the website operator. If you are the website operator please use the ionCube Loader Wizard to assist with installation.
مشکل از کجا میتونه باشه
