Solved. Seems like the UniversalClassLoader.php was declared twice. I just comment it out at one of the plugin (either my in-house plugin or your Amazon plugin), then it is good to go.

Thanks for the lead. It might very be a conflict with our in-house built plugin.

If myplugin is already on, trying to load ‘Amazon Web Services’:
Fatal error: Cannot redeclare class Symfony\Component\ClassLoader\UniversalClassLoader in /www/unartforpeace.org/html/wp-content/plugins/amazon-web-services/vendor/aws/Symfony/Component/ClassLoader/UniversalClassLoader.php on line 62

If ‘Amazon Web Services’ is on, trying to load myplugin:
Fatal error: Cannot redeclare class Symfony\Component\ClassLoader\UniversalClassLoader in phar:///usr/share/php/aws.phar/Symfony/Component/ClassLoader/UniversalClassLoader.php on line 62

Feedback would be very most welcome.
