I configured curl with SSL certificate in php.ini according to this but still I got the error cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html).
I thought the error may have occured due to mod_openssl module of apache server, and I tried to enable mod_openssl on Apache server 2.4.17, wampserver 3.0 but when I did wampserver could not start. After I disabled mod_openssl back, started fine.
What is the problem? How do I fix the curl SSL certificate error?
I am using: wampserver 3.0 apache server 2.4.17 php 5.6.16
