Whilst the plugin tries to work on the most common PHP environments, it currently requires PHP 5.4 or higher.
As official security support drops for PHP 5.6 at the end of 2018, it is strongly recommended to upgraded your WordPress hosting environment to PHP 7, ideally, PHP 7.1 or 7.2, as 7.0 will also stop being supported in December, 2018.

Your current PHP version is:
Please ensure that wp_site->wp_uploads_path; ?>

This is a library that allows the plugin to better export your static site out to services like GitHub, S3, Dropbox, BunnyCDN, etc. It's usually an easy fix to get this working. You can try Googling "How to enable cURL extension for PHP", along with the name of the environment you are using to run your WordPress site. This may be something like DigitalOcean, GoDaddy or LAMP, MAMP, WAMP for your webserver on your local computer. If you're still having trouble, the developer of this plugin is easger to help you get up and running. Please ask for help on our forum.
Due to the nature of how static sites work, you'll need to have some kind of permalinks structure defined in your Permalink Settings within WordPress. To learn more on how to do this, please see WordPress's official guide to the Settings Permalinks Screen.
