I know there are quite a few questions already asked in regards to this, but I couldn't find one that answers my current question exactly.
Actually 2 days ago,my app is perfectly running for Facebook login and registration .but now it shows below error .
i have done all the required steps and it was running perfectly.
Switch to a registered test user or ask an app admin for permissions. This Error Comes because the app which is used to login in facebook , is in developement mode. So, other users can't login with their facebook. To Solve this error you have to make the App live.
Go to https://developers.facebook.com/ , then to My Apps -> Developer Settings -> Delete my Developer Account.
Newly created apps are automatically set to Dev Mode by Facebook so that developers can configure and test app integrations before submitting the app for review.
Apps in Development mode can only request permissions from role users, and only permissions with standard or advanced access levels (applies to Consumer apps only). Similarly, features will only be active for role users, and only features with standard or advanced access levels (Consumer apps only).
Logon Facebook Developer Account
Go to Apps and select your APP and click on the Status & review then select "YES" access public then click confirm button to finished.
