I tried to enable Facebook Insights for my web. I added my page's APP_ID
to fb:admins
to enable every admin of my page to access Insights when logged into Facebook as Page. But when I try to save the dialog message appears:
The app ID "123,123,123,123,123" specified within the "fb:app_id" meta tag was invalid.
I double checked my app ID and it's correct.
To link Domain Insights to an app rather than a user, you need to use the fb:app_id
tag:
<meta property="fb:app_id" content="your_app_id" />
