If you get the error “SSL certificate problem: unable to get local issuer certificate”.
Step 1. Download the latest cacert.pem file from here.
Step 2. Copy the downloaded cacert.pem file to a directory where WAMP can access it. For example, you might want to save it in a directory like C:\wamp64\bin\php\phpx.x.x\extras\ssl\ (replace x.x.x with your PHP version).
Step 3. Open your php.ini file located in your PHP installation directory (e.g., C:\wamp64\bin\php\phpx.x.x\php.ini).
Step 4. Change these
curl.cainfo = “C:\wamp64\bin\php\phpx.x.x\extras\ssl\cacert.pem”
openssl.cafile=”C:\wamp64\bin\php\phpx.x.x\extras\ssl\cacert.pem”
Step 5. Restart WAMP.
