Answer 1

I was getting the same error and inspecting apache error logs I got the following

CURL error (60): SSL certificate problem: unable to get local issuer certificate

This was being caused by curl calls from the OpenID plugin.

The following worked for me. Source: https://stackoverflow.com/a/21114601/3826642

1. Use this certificate root certificate bundle: https://curl.haxx.se/ca/cacert.pem

2. Copy this certificate bundle on your disk. And use this on php.ini

   curl.cainfo = "path_to_cert\cacert.pem"

Be sure to restart the server after you make changes.
