I am using eBay API PHP SDK and get this error when running on my local WAMP server in Win 7:
Fatal error: Uncaught exception 'GuzzleHttp\Exception\RequestException' with message 'cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)' in C:\vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php on line 187 ( ! ) GuzzleHttp\Exception\RequestException: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html) in C:\vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php on line 187
