ionCube encoding method is used to secure the PHP files. It helps to encrypt PHP files and read encrypt PHP files.
However, to decode the encrypted PHP files, ionCube loaders should install on the server as an additional requirement. To use software like softaculous need ioncube install on server. installing of Ioncube loader in DirectAdmin is very easy.
Login your terminal as root, type:
./build set ioncube yes
The “./build set” command only sets the option in the options.conf, so you only need to do that once to enable the feature, then install the item after it’s enabled.
