I’m sorry to hear that you are facing issues with your website’s featured image not displaying correctly on Facebook when sharing links. This problem can be related to various factors. Here are some steps you can take to troubleshoot and potentially resolve the issue:

Also, make sure to set a custom Open Graph/Social Preview image for individual posts/pages by uploading a featured image or setting it through the Rank Math Block Editor sidebar.
-
Image Dimensions & Format: Verify that the image you are using meets the recommended dimensions of 1200px X 630px and is in a supported format like jpeg, png, gif, or WebP for Facebook Open Graph.
-
Cache and Compression Issues: Sometimes, cache plugins or gzip compression settings can interfere with how Facebook detects Open Graph tags. Check if your cache plugin is pushing Open Graph tags too far down in the source code or if gzip compression is enabled. If so, consider moving inline CSS to a file and disabling gzip compression.

Facebook App ID: Ensure that you have configured the Facebook App ID in Rank Math under WordPress Dashboard โ Rank Math SEO โ Titles & Meta โ Social Meta. Adding the Facebook App ID can help resolve some sharing-related issues.
