 * Hi
 * I’m trying to get the Mailchimp for WooCommerce to work with our site and getting
   a couple of errors. The site is running on IIS if that makes any difference? 
   SSL certificate is via Cloudflare.
 * 1.
    Mailchimp says: API Request Error – 500 :: CURL error :: SSL certificate 
   problem: unable to get local issuer certificate on 1657 in C:\inetpub\wwwroot\[
   OUR WEBSITE]\wp-content\plugins\mailchimp-for-woocommerce\includes\api\class-
   mailchimp-api.php
 * 2.
    CURL error :: SSL certificate problem: unable to get local issuer certificate
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fssl-certificate-errors%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * [@mrmodo](https://wordpress.org/support/users/mrmodo/) thanks for writing in 
   about this issue – but unfortunately this is outside the scope of the plugin 
   support.
 * This is a CURL error which tells you specifically that your server is not configured
   properly to use the “local issuer certificate”. You will be running into this
   if you made any external CURL requests – not just for Mailchimp.
 * I would contact your web hosting company – tell them the exact same thing that
   you told us here – and they should be able to fix the problem for you.

 * Thanks
 * FYI
 * I fixed it using this
 * [https://martinsblog.dk/windows-iis-with-php-curl-60-ssl-certificate-problem-unable-to-get-local-issuer-certificate/](https://martinsblog.dk/windows-iis-with-php-curl-60-ssl-certificate-problem-unable-to-get-local-issuer-certificate/)
 * 1) Download “cacert.pem” from here: [http://curl.haxx.se/docs/caextract.html](http://curl.haxx.se/docs/caextract.html)(
   [https://curl.haxx.se/ca/cacert.pem](https://curl.haxx.se/ca/cacert.pem))
    2)
   Save the cacert.pem to the directory on the server, where the PHP version you
   use, resides: 3) Update the php.ini to point to this file curl.cainfo = “C:\php\
   extras\ssl\cacert.pem”
 * Restart IIS

 * [@mrmodo](https://wordpress.org/support/users/mrmodo/) glad to hear you got that
   handled 🙂 Also – thanks for explaining to other folks how you got that problem
   fixed. It will be very helpful for anyone running into that issue.
 * If you feel the plugin has done it’s job after you’ve got everything in sync –
   we would greatly appreciate a fair review of our plugin if you have the time 
   to do so.
 * Thanks again.
