cURL error 60 on WordPress [resolved]

You are receiving a PHP Fatal error in WordPress cURL Error 60: SSL Certificate Problem? In this article I will show you how to fix it.

Often, cURL error 60: SSL certificate problem: unable to get local issuer certificate error occurs when we try to call the API with the secure https:// protocol in the request URL.

Why This Error Occurs?

Just go to your API call code and try to run request URL with only http:// protocol. You can’t see the error anymore because secure API calls require an SSL certificate.
