    I’m seeing the same problem:

    [2021-12-09 01:19:14] Setting up

    My server:
    * Simply Static 2.1.5.1
    * WordPress 5.8.2
    * PHP 7.4.3
    * Nginx front end serving static files, proxying WP requests to an Apache backend
    * The site is publicly reachable, no authentication required.

    I will third this as I’m getting the exact same error but with a slightly different configuration:

    ~~ Simply Static Plugin Version 2.1.5.6
    ~~ WordPress 5.9.2
    ~~ LAMP stack with Amazon Linux 2, Apache and MySQL
    ~~~~~ PHP 7.4.28

    Thanks!

    I upgraded SimplyStatic to version 2.1.5.7 and am still having the same issue.

    Thanks!

    I was able to fix this on a Debian bullseye system by doing:

    sudo apt install php-xml

    HTH!
