Hello,
We apologize for the issue you are facing with the social media thumbnail not displaying correctly on Facebook. Here are a few things you can check to resolve this:
-
Ensure the Image is Set: First, confirm that you have added the Facebook sharing image through the Rank Math Meta Box. You can do this by checking the social settings for the specific post or page.

-
Check Image Dimensions and Format: Make sure that the image you uploaded meets Facebook’s recommended dimensions of 1200px X 630px. Additionally, ensure that the image format is supported (JPEG, PNG, GIF, WebP, or AVIF).
-
Use the Facebook Sharing Debugger: You can use the Facebook Sharing Debugger to scrape your URL again. This tool can help identify any issues with how your content is being shared on Facebook.
-
Clear Cache: If you are using a caching plugin, clear your cache to ensure that the latest changes are reflected.
If you’ve checked all these points and the issue persists, please reply to this ticket with your site URL so that a human agent can assist you further. Thank you for raising this concern!
