Fix Vultr Plesk Setup HTTP ERROR 500 for Server & WordPress WooCommerce & Wp Rocket caching plugin Configuration

I am seeking an experienced server administrator to fix an HTTP Error 500 that I am getting on my Vultr Plesk server, as well as configure php-fpm, Hosted WordPress WooCommerce plugin WP Hide & Security Enhancer and the caching plugin WP Rocket. I do not need any additional server configuration. This project requires a considerable amount of technical knowledge and expertise so please only apply if you have the necessary qualifications and skillset.

Server access will be given through TeamViewers or anydesk.
