cURL error 60: SSL certificate: unable to get local issuer certificate

I am trying to send an API request using Stripe but get the error message: > cURL error 60: SSL certificate problem: unable to get local issuer certificate This is the code I am running: public function chargeStripe() { $stripe = new Stripe; $stripe = Stripe::make(env('STRIPE_PUBLIC_KEY')); $charge = $stripe->charges()->create([ 'amount' => 2900, 'customer' => Input::get('stripeEmail'), 'currency' => 'EUR', ]); return Redirect::route('step1'); } I searched a lot on Google and lots of people are suggesting that I download this file: [cacert.pem][1], put it somewhere and reference it in my php.ini. This is the part in my php.ini: curl.cainfo = "C:\Windows\cacert.pem" Yet, even after restarting my server several times and changing the path, I get the same error message. I have the ssl_module enabled in Apache, and I have php_curl enabled in my `php.ini`. I have also tried another fix which suggests that I add these lines to my cURL options: curl_setopt($process, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem'); curl_setopt($process, CURLOPT_SSL_VERIFYPEER, true); Where do I add options to my cURL? Apparently not through the command line, since my CLI doesn't find the command "curl_setopt" [1]: http://curl.haxx.se/ca/cacert.pem
