Hi, I encountered a similar fatal error when activating the plugin. The error persisted and the plugin had to be manually removed to resolve it. Here is error from the log:
Got error ‘PHP message: PHP Fatal error: Uncaught Error: Call to undefined function wp_create_nonce() in /wp-includes/functions.php:1894
