But from what I see you are trying to use a secured TLS encryption while communicating with smtp.gmail.com, but your server doesn’t have a valid certificate. It’s misconfigured. The easiest way to fix that – contact your hosting company support to fix that. * Your last resort may be trying to use this code snippet: [https://gist.github.com/slaFFik/c1d7d4249f47da7195fb973109952090](https://gist.github.com/slaFFik/c1d7d4249f47da7195fb973109952090) * Put in in a child theme `functions.php`. It will remove the certificate check, but in that case, Google still may reject the connection. * Thread Starter [Simon](https://wordpress.org/support/users/flaxion/) * (@flaxion) * [8 years, 5 months ago](https://wordpress.org/support/topic/test-mail-error/#post-9817311) * Thank you for your reply. I tried changing the configuration according to the Google Suite guidelines but nothing worked. I also checked that ‘Allow less secure apps’ was turned on (it was). * I then tried using the Gmail configuration with the API solution instead and now it gives this error instead: * Versions: WordPress: 4.9.1 WordPress MS: No PHP: 5.6.11 WP Mail SMTP: 1.2.2 * Params: Mailer: gmail Constants: No Client ID/Secret: Yes Auth Code: Yes Access Token: No * Server: OpenSSL: Yes PHP.allow_url_fopen: Yes PHP.stream_socket_client(): Yes PHP.fsockopen(): Yes PHP.curl_version(): Yes Apache.mod_security: No * Debug: cURL error 60: SSL certificate problem: unable to get local issuer certificate( see [http://curl.haxx.se/libcurl/c/libcurl-errors.html](http://curl.haxx.se/libcurl/c/libcurl-errors.html)) cURL error 60: SSL certificate problem: unable to get local issuer certificate( see [http://curl.haxx.se/libcurl/c/libcurl-errors.html](http://curl.haxx.se/libcurl/c/libcurl-errors.html)) Error while sending via Gmail mailer: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see [http://curl.haxx.se/libcurl/c/libcurl-errors.html](http://curl.haxx.se/libcurl/c/libcurl-errors.html)) cURL error 60: SSL certificate problem: unable to get local issuer certificate( see [http://curl.haxx.se/libcurl/c/libcurl-errors.html](http://curl.haxx.se/libcurl/c/libcurl-errors.html)) * Plugin Author [Slava Abakumov](https://wordpress.org/support/users/slaffik/) * (@slaffik) * [8 years, 5 months ago](https://wordpress.org/support/topic/test-mail-error/#post-9819630) * [@flaxion](https://wordpress.org/support/users/flaxion/) * You don’t have a proper SSL certificate on your server. Ask your hosting support to fix that. That’s not the same as enabling SSL on your site.
