Have you noticed an incorrect post thumbnail appearing when you share your articles on Facebook? Many of our users have complained about this. In this article, we will help you fix the wrong Facebook thumbnail issue in WordPress.
There are many reasons that can prevent Facebook from correctly guessing the correct thumbnail image. One of the most common reasons is having multiple images in the og: imagen tag where your featured image is smaller than the rest of the images.
Facebook uses Open Graph (og) tags and many WordPress plugins like WordPress SEO by Yoast automatically add them to your site to avoid missing the thumbnail issue.
Other causes include caching plugins, CDN issues, missing open graph meta tag for thumbnail image. etc. It's really hard to guess what's causing the problem because no specific error messages are displayed when using the debug tool.
Let's take a look at how to fix the wrong Facebook thumbnail issue.
If you're sharing an article on your Facebook page and it doesn't pick up the correct thumbnail image, you can click the upload link to upload the image you want to use.
Note:The image you upload is stored in the photos section of your Facebook page. You can remove the image from the photos if you want. Facebook will continue to display the image you uploaded as the article's thumbnail on your timeline.
However, this solution does not affect other users. That is, if other users share your article, then it may still display the wrong thumbnail.
But the next solution takes care of that part.
If you are using the WordPress SEO by Yoast plugin, then you can easily set up a specific thumbnail image for Facebook.

Just add your Facebook thumbnail image there, and this will fix the problem in most cases.
However, if it still shows the wrong thumbnail, you may need to reset your Facebook cache.
