Recently, we wrote a guide on using Xampp with Drupal 8 for local development.
After reading the guide, one of our users asked,
How do you fix the cURL 60 SSL error that I keep getting?
The cURL SSL 60 error occurs when you’re trying to install Drupal module by copying the FTP link from drupal.org into the “Add modules” screen.
This error is caused by the default SSL certificate provided by Xampp.
