Posting wrong photo on social media

Install Yoast’s WordPress SEO and fill out the socia media sections so the proper Open Graph tags are set. Then use the Facebook Debugger to see what Facebook thinks you want shown.

Thanks, I’ve already done that. The problem doens’t affect only Facebook. The issue is with almost ALL social media channels as I wrote Google Plus, Linkedin, Pinterest… Each of them turns out differently when it comes to show the single post image and text content.

link to your site, please

I didn’t built the website, the owner just asked to help him fix this issue that, I’m quite sure, the web developer who runs the hosting service started, changing the WP theme code.
If you copy and paste a post url onto some socials you will see that each one of them shows different results.
Cheers,

I looked at https://www.benesserenaturale.com/getting-a-perfect-suntan-things-we-should-do-immediately/ and noticed it had two og:image tags:

<meta property="og:image" content="https://www.benesserenaturale.com/it/wp-content/uploads/2016/05/Scrub.jpg" />
<meta property="og:image" content="https://www.benesserenaturale.com/it/wp-content/uploads/2016/05/maggio_senzascritta-1-638x1024.jpg" />
<!-- / Yoast SEO plugin. -->

Should only have one tag otherwise things will get confused.

Thank you MarkRH, those two tags comes both from Yoast anyway. Yesterday Yoast wasn’t installed and the problem was already there.
