The ionCube Loader fails to install in Plesk under PHP version 8.2:
PLESK_INFO: tar: ioncube/ioncube_loader_lin_8.2.so: Not found in archive
tar: Exiting with failure status due to previous errors
Downloaded ionCube Loaders archive doesn't contain expected ioncube_loader_lin_8.2.so file
This is a Plesk bug PPPM-14059, which will be fixed in future updates not allowing the ioncube loader installation on PHP 8.2 as this handler version is not supported by the ionCube vendor yet as mentioned at ionCube home.
Switch to one of the supported PHP versions. e.g: PHP 8.1 or lower.
