The following required properties are missing: fb:app_id

Hello, we apologize for the inconvenience you are facing with the error message “The following required properties are missing: fb:app_id” even after entering Facebook’s Application ID in Rank Math.

If you have followed all the steps and entered the Facebook App ID in Rank Math but the error message still persists, there might be a few reasons for this issue:

1. Caching: Facebook follows a caching system that stores your site’s metadata. Sometimes, it may take up to 30 days for the cache to refresh. However, Rank Math pings Facebook whenever your post gets updated to clear the cache. You can try updating your post and checking if the error disappears after some time.

2. Scrape Again: After saving the changes in Rank Math, you should clear your website cache & server cache (if any) and then use the Facebook Debugger tool to confirm if the error is no longer present. You may need to click on Scrape Again in the Debugger tool to force it to fetch the latest version of your page.

3. Open Graph Tags: Ensure that the Open Graph tags, including the og:image tag, are correctly set up in your page source. Facebook checks for these tags in the first 50Kbs of the page source. If there are any issues with these tags, it might cause the error message to persist.

If you have tried these steps and are still facing the issue, please feel free to reach out to our support team by clicking here. Our team will assist you further in resolving this issue promptly.

We appreciate your understanding and patience as we work to resolve this issue for you. Thank you for bringing this concern to our attention.
