Facebook Login Problem with Custom Domain


Hello everyone,

I have used Facebook login for several times for several custom domains. But I am now getting a common URL Redirect problem when trying to login. I am using Modulus for my server and configured

ROOT_URL on server as “http://100foot.com” (site URL is just an example),

APP DOMAINS and SiteURL on Facebook as “http://100foot.com” ,

Valid OAuth redirect URIs on Facebook as “http://100foot.com/_oauth/facebook?close”, and enabled all logins.

These are same for my other applications, but they work. I would be grateful if you can help. Thanks.
