                    <p> 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.
