The app ID specified within the "fb:app_id" meta tag was invalid
facebook, facebook-insights, facebook-opengraph
Solution
Only personal IDs are allowed in the `fb:admins` meta tag. Application IDs won't work, even though they are actually valid (in contrary to what the error message says).
Optionally, it may also work with page_id:
<meta property="fb:page_id" content="395450240451647" />
The suggested `app_id`didn't work at all :(
Problem
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.
