I am using socialite in Laravel 5 to setup facebook login. I followed the instructions carefully until I got stuck with the following error
cURL error 60: SS
you did not read the error carefully, now read it carefully
cURL error 77: error setting certificate verify locations: CAfile: D:\XAMPP\apache\bin\curl-ca-bundle.crt CApath: none (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
it means you are missing a file called curl-ca-bundle.crt to verify certificate locations, so you just need to put this(curl-ca-bundle.crt) file into your XAMPP\apache\bin\ folder and everything is fine error 77 has gone.
curl-ca-bundle.crt, to download the file you can use this link https://github.com/nirmalkumar98/nk
