Sometimes, when cutomers use their gmail account to send out emails throught their website, e.g WordPress, they may encounter the error below:

[cc]cURL error 60: SSL certificate problem: unable to get local issuer certificat[/cc]

In order to fix it we need to download a CA cert file from https://curl.haxx.se/docs/caextract.html and include it in website’s php.ini file:

[cc]curl.cainfo = “/usr/local/php55/lib/cacert.pem”[/cc]
