which version?

Zend or ionCube version

whats the difference? and the test.php failed on both :(

The setting of extension_dir in the php.ini file is not a directory or may not exist and run time loading will not be possible. You do not need write permissions on the extension_dir but for run-time loading to work a path from the extensions directory to wherever the Loader is installed must exist.

You must ask your hosting company to install either ioncube or zend. Both versions have no difference at all. The only important thing is your server confuguration. So discuss it with your hosting.
