Yoast is failing to add the og:image tag

Can you please let us know what image you have set for the og:image in the settings? One reason why the og:image may not be output on the page is if it doesn’t meet the image requirements. The image you use must be the minimum dimensions of 200 x 200 pixels, and the size of the image file must not exceed 8 MB. You can read more about this here: https://developers.facebook.com/docs/sharing/webmasters/images/

Hello,

yes, I used this image in the default settings: https://innerflowyoga.de/wp-content/uploads/2019/12/ify_blumen-quer-1.jpg.

I think it meet the image requirements.

The image is output in the source code when we used it on our local test environment for either the featured image and the Facebook specific image. This means it’s not the image itself. Please try removing the image, reselecting it from the media section, and updating the post.

If it continues to not show in the source code for your site, we would like to rule out any plugin or theme conflicts that may occur. The fastest way to do this is to?deactivate all non-Yoast plugins and switch to a standard theme?like?Twenty Nineteen.?

Test this on your development or staging site, if you have one. If not, we recommend using the?Health Check & Troubleshooting?plugin. This plugin allows you to run a conflict check?without affecting normal visitors to your site.

As we can imagine that you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process:?How to check for plugin conflicts.

Closed due to inactivity.

Thanks for closing. I figured it out, thanks for the advises.

This is the Plugin which cause the issues:

<meta property=”og:image”
<meta property=”og:image:secure_url”
<meta property=”og:image:width” content=”599″ />
<meta property=”og:image:height” content=”449″ />
