Problem Php 7 and ionCube

Hi, after I setted php 7 on my plesk panel 12.5 and after I opened my site I receive this error:

Site error: the file /var/www/vhosts/MYSITE/httpdocs/index.php requires the ionCube PHP Loader ioncube_loader_lin_7.0.so to be installed by the website operator. If you are the website operator please use the ionCube Loader Wizard to assist with installation.

How can I solve?
Thank you so much
