I have l5.2 and I followed this steps in hooking sparkpost and laravel and I reverted my services and mail.php
to its original configuration:

But I get this error:
cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
