i can using google, facebook, twitter sso-plugin on my nodebb forum, my nodebb version is: v1.13.4-5
i found plugin in github not work, anybody have the same issues like me and how can you fix it?
...or does NodeBB make sure all requests and posts to /admin/*
are administrators?
You don't have to. NodeBB core makes sure all requests to those routes are from admins.
