But when I activate the theme I find this error Site error: the ionCube PHP Loader needs to be installed. This is a widely used PHP extension for running ionCube protected PHP code, website security and malware blocking. Please visit get-loader.ioncube.com for install assistance.
I enable "ioncube_loader" or "ioncube_loader_4" in "Select PHP version" but now this error

by this version of the ionCube Loader.
From the error message, it appears that the license for the template is not being recognized properly, so it can't be decoded. I would recommend sending that error over to the developer of the template so they can review it. They may need to give you a different set of files so you can run it on your current hosting plan.
