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
If anyone is running Windows with Plesk and they get this error.
You must ensure that the curl.cainfo path is inside the Plesk PHP directory otherwise you will get the error above even with the fix.
curl.cainfo = "C:\Program Files (x86)\Parallels\Plesk\Additional\PleskPHP55\extras\ssl\cacert.pem.txt"
Fixed for me. Hope this helps someone, someday, somewhere.
