Facebook API "This app is in development mode"

Question

I know its a little bit late but someone may find this useful in future.

STEP 1:

Login to facebook Developer -> Your App

In Settings -> Basic -> Contact Email. (Give any email)

STEP 2:

And in 'App Review' Tab : change

Do you want to make this app and all its live features available to the general public? Yes

And you app will be live now ..

Click app review and Turn on the Make your app Public toggle. Save changes

This problem occurs when we set our app as unavailable to the public. 

STEP 1

Open Facebook developer account

STEP 2

Select your application

STEP 3

Click the app Review tab.

Change switch value no to yes. See picture below.

After this your app is live.

• Development mode is for testing
• Go to https://developers.facebook.com/apps, then App Review -> Select No for Your app is in development and unavailable to the public
• Go to Roles -> Testers, enter the Facebook user Id of the users you want to enable testing

Follow these basic steps to fix this problem,

Step 1: Go to Dashboard,

Step 2: Go to "App Review" tab,

Step 3: Enable the "Make test public?" option, Like Below image,

I had also faced the same issue in which my FB app was automatically stopped and users were not able to login and were getting the message "app is in development mode.....".

Reason why FB automatically stopped my app was that I had not provided a valid PRIVACY policy & terms URL. So, make sure you enter these URLs on your app basic settings page and then make your app PUBLIC from app review page as described in above posts.

in your app dashboard check status to on
