Thumbnail option not shown though theme has thumbnails

Do you set your featured image like this? https://en.support.wordpress.com/featured-images/#setting-a-featured-image

I don’t know about Thesis, so I can’t speculate, but it’s possible that Thesis uses some different thumbnails mechanism which is not the same thing. YARPP is built to use the WordPress-supported mechanism.

@mitcho: No, I don’t set the thumbnails like this, I configure the post thumbnails using the “Thumbnail Image” function in the Thesis theme.

Hmm, that’s too bad. In that case I don’t think I can help you. I suggest you contact Thesis and see if they have an option to use the WordPress-builtin thumbnail feature instead.

For those who have the same problem:

In Underscore_s the function is out-commented, so just remove the // on line 45

@kingmaico: Sorry, what source file and what line of code dou you mean?

I looking theme.php and functions.php, but did not find anything.

In the Underscores theme (https://underscores.me/) > functions.php line 45
This is to enable uploading featured images to a post or page.

You use another theme, so it would be different.

But reading your post, I believe you can upload featured images but cannot use them. Is that correct?

Almost. I specify a thumbnail image (not a featured image) for each post in the “post thumbnail” field, but the plugin tells me that no thumbnails are available.

YARPP only works with the standard featured image.

It shows featured image, but it shrinks it instead of cropping. That looks not really nice: https://inln.me/cinema-2/films/tayna-perevala-dyatlova-dyatlov-pass-incident-2013/ as well as any post.

Any chance to fix?

Hi goutm. Please see the FAQ under the section “Why aren’t the right size thumbnails being served?” I recommend using the “Regenerate Thumbnails” plugin to get correctly sized thumbnails for past posts.
