Featured image is not being fetched by social medias

Does anybody have encounter an issue about featured images while sharing posts on social medias (Facebook, twitter)?

In my case, the featured images are not being fetched by twitter and facebook and I had changed the single post template, then demo page, but nothing works.

Hello support team ! I couldn’t provide the site link here as this is the forum page. If you could assist me on email then I will provide the site URL for sure. If can’t then please guide me how can I fix this serious issue 🙁

I also had the same problem. I was told that I did not have data source, that is why the images do not appear on social sharing. In order to fix that, yoast seo plugin was installed -> https://kb.yoast.com/kb/getting-open-graph-for-your-articles/

After installing yoast seo also, you need to set featured images of less than 300kb, for the image to show in the social sharing of Whatsapp. You could use Photoshop or any plugin to optimize images. Else, you could use this online website to optimize images -> http://www.resizeimage.4u2ges.com/ .
