Hello,
I’m sorry to hear about the issue you’re facing with the thumbnails not displaying after transferring your site. This can sometimes happen due to various reasons related to the settings in your SEO plugin or the way the images are being handled after migration.
Here are a few steps you can take to troubleshoot and potentially resolve the issue:
-
Check Schema Settings: Ensure that the Schema module is enabled in Rank Math. You can do this by navigating to WordPress Dashboard → Rank Math SEO → Modules and confirming that the Schema module is active.
-
Set Featured Images: Make sure that each post has a featured image set. If you have videos, ensure that you have enabled the options for autodetecting video thumbnails in Rank Math settings. You can refer to this guide on how to fix Missing ThumbnailUrl Error in Schema Markup for more details.
-
Open Graph Settings: Check your Open Graph settings in Rank Math to ensure that the correct images are set for social sharing. You can set a default Open Graph image under WordPress Dashboard → Rank Math → Titles & Meta → Global → OpenGraph Thumbnail.
-
Regenerate Thumbnails: If the images were not properly transferred, you might consider using a thumbnail regeneration plugin. This can help regenerate the thumbnails for your media library, ensuring they are correctly linked.
-
Clear Cache: If you are using any caching plugins or services, clear the cache to ensure that the latest changes are reflected.
If these steps do not resolve the issue, please reply to this ticket with your site URL so that a human agent from our support team can assist you further. Thank you for raising this concern, and we hope to help you get it sorted out soon!

The JPG thumbnail is displayed, but the WebP thumbnail is not.
So I added the code below and it was solved.
I think Rank Math should be aware of this issue as well.
// Remove Rank Math OG Tags
add_action( ‘rank_math/head’, function() {
remove_all_actions( ‘rank_math/opengraph/facebook’ );
});
Or will reinstalling Rnak Math fix the problem even if I don’t add the code?

Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
All posts are applicable because all posting thumbnails on the site listed in Sensitive Data are all WebP.
Hello,
We no longer see any og:image from Rank Math on your site’s source code. It appears the snippet you added has removed those meta tags.
The og:image uses primarily the image you set in the social tab within the Rank Math meta box while editing the page(OpenGraph image). If you set none, it then tries to use the featured image. If this is not available it uses the first image in the post. Where the post/page doesn’t have any image it then uses the default OpenGraph image set at WordPress dashboard > Rank Math > Titles & Meta > Global Meta > Opengraph Thumbnail.
We hope this helps. Please let us know if you have further questions or concerns.
Thank you.
I added the code below because the thumbnail didn’t show up, which is why you can’t see the og:image of Rank Math.
If I remove the code below, the WebP thumbnail will not be displayed on any site other than the Thread.
// Remove Rank Math OG Tags
add_action( ‘rank_math/head’, function() {
remove_all_actions( ‘rank_math/opengraph/facebook’ );
});
Hello,
If you want your thumbnails to show correctly, you’ll need to keep Rank Math’s OG tags enabled. You can still use WebP for your images, but we recommend also having a JPG or PNG fallback to ensure consistent display across all platforms.
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Are you telling me to delete the code “// Remove Rank Math OG Tags” and use the JPG or PNG format for the thumbnail?
Hello,
If you would like Rank Math to generate the Open Graph meta tags, you’ll need to remove that filter code.
Regarding the WebP image format, it is supported by most social media platforms, as explained here: https://joost.blog/use-avif-webp-share-images/
However, if it is causing issues on your end, you can try changing the image format to see if that resolves the problem.
Hope that helps, and please don’t hesitate to let us know if you have any other questions.
Thank you.
