Hi, I suggest you install it manually first. Download the files related to your operating system from the official website,
https://www.ioncube.com/loaders.php
And refer to the installation script to install
Put the so file of the corresponding php version into /usr/local/ioncube/ and then add configuration content to the corresponding php version configuration file
Such as the so file of php8.0: /usr/local/ioncube/ioncube_loader_lin_8.0.so
The configuration file adds:
;ionCube
zend_extension = /usr/local/ioncube/ioncube_loader_lin_8.0.so
Install script: /www/server/panel/install/ioncube.sh
