(1/1) RequestException cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Hey can anybody help me with this issue ? I have been trying to get my Facebook socialite up and working but after using stateless() to get rid of the invalidStateException i encountered with this error . Before pointing me to the other links i've already tried all the ways as directed in the stack overflow and other google searches . I've downloaded and saved the cacert.pem file to my C:\wamp64\bin\php\php7.2.18\extras\ssl path and also changed the curl.cainfo ="C:\wamp64\bin\php\php7.2.18\extras\ssl\cacert.pem" in my php.ini file still i could not figure what is wrong with my code . Please Help
