Do not ever modify files in the vendor/ folder. Ever. They can and will be
overwritten on the next composer update you run.
Here is my Solution for WampServer
I am using PHP 7.1.9 for my WampServer, so change 7.1.9 in the example below
to the version number you are currently using.
1. Download this file: http://curl.haxx.se/ca/cacert.pem
2. Place this file in the C:\wamp64\bin\php\php7.1.9 folder
3. Open php.iniand find this line:
;curl.cainfo
4. Change it to:
curl.cainfo = "C:\wamp64\bin\php\php7.1.9\cacert.pem"
5. Make sure you remove the semicolon at the beginning of the line.
6. Save changes to php.ini, restart WampServer, and you're good to go!
