Zend guard decryption module cannot be found?

Zend Guard Run-time support missing!

Open the web page and this is it. But I also downloaded zend’s decryption module and configured it
zend_extension=/usr/lib64/ZendGuardLoader.so

<code>zend_loader.enable=1
zend_loader.disable_licensing=0
zend_loader.obfuscation_level_support=3
</code>

The server also showed that it was successfully installed, and php-fpm was also restarted. Why is the running module still missing?
