Erreur de boucle 60: certificat SSL: Impossible d'obtenir un certificat local émetteur

All of the answers are correct ; but the most important thing is You have to find the right php.ini file. check this command in cmd " php --ini " is not the right answer for finding the right php.ini file.

if you edit

curl.cainfo ="PATH/cacert.pem"
and check

then curl.cainfo should have a value. if not then that's not right php.ini file;

*I recommend you to search *.ini in wamp/bin or xxamp/bin or any server you use and change them one by one and check it. *
