Hi Bach,
So purchased SSL certificate for site, but still get:
Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings.
Enforce HTTPS - enabled
Use Strict Mode for Redirect URLs - enabled
Read that I should enable OAuth redirect, but this gives this error:
URL Blocked: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs
Need help to get this to work, please.
