Yoast integration with cross origin/CDN issue

Thanks for your report.

This is something that needs to be resolved on the Yoast SEO side because their metabox is outside of our control

To provide a little bit of context:

The Web Stories editor runs in a strict and more secure mode called cross-origin isolation. This is usually the case when video optimization is enabled in the Web Stories settings (which we recommend!)

With cross-origin isolation, it is mandatory for images/styles/etc. from external sources to have appropriate CORS headers and also the crossorigin="anonymous" attribute.

In your case it looks like your images have the correct CORS headers, but Yoast is not adding this attribute.

You can learn more about cross-origin isolation at https://web.dev/cross-origin-isolation-guide/

Thanks for rapid response! I set the CORS headers in last days for images.

That’s a great first step.

Now it would be on Yoast to add crossorigin="anonymous" to all images they load in the meta box. Either by default or only when cross-origin isolation is in place.

In the meantime, you can work around this by disabling video optimization on the settings page.

I deactivate the option and after this the images ints showing normally.

About the video optimization: it’s only for reduces the size, or its work in play videos from readers? I begin to upload the TikTok and Instagram reels, and one of next updates (in public roadmap) its mentioned to cropping the videos (“Remove off-screen parts of a video/image”)

The Offload plugin sends video from S3 and i mark the option to don’t mantain the image in original server (because i have only few GB disk free to use)

The video optimization setting unlocks features like video compression, video muting, video trimming, webcam recording. And yes, in the future also for cropping off-screen parts of videos/images. That’s why we recommend keeping it enabled (and might even not allow you to disable it anymore).

Hi! You know how i can find the yoast tab in WordPress plugin editor. The Yoast get a update today, and the problem still persist. And the devs mark other topic as resolved =(

I can try to open new topic in Yoast forum, and i begin to search this in editor to add the crossorigin for myself =(

You can toggle the Yoast SEO meta box using this button in the lower corner:

And the devs mark other topic as resolved

That’s unfortunate, since it’s really something that Yoast need to resolve on their end.

Thanks! I found the box here here, and i tried to know how to add an filter with the crossorigin tag, but until now i cant found any references in forums and other websites.

I will create another topic on Yoast forums to get more support.
