Your install of PHP doesn’t know how to handled SSL connections to remote services via cURL
It’s beyond the scope of this forum for such an issue. EasyPHP is not as Easy as it makes out to be.
And google isn’t throwing up anything initially useful to get started/solve this issue.
Usually you’ll find that your CA Cert bundles are out of date or non existant as easyPHP didn’t bother to grab them.
