This thread is resolved. Here is a description of the problem and solution.
Problem: I get this error message when trying to activate the WPML plugin: Plugin could not be activated because it triggered a fatal error. Fatal error: Call to undefined function WPML\Container\make() in /volume1/web/wordpress/wp-content/plugins/sitepress-multilingual-cms/sitepress.php on line 173.
Solution: The Make Builder plugin from The Theme Foundry was the one causing the issue. Once deactivated, everything went back to normal.
