Regenerating one thumbnail resets another

Hi @codings ,

To clarify – this is happening only on featured products?

How are those products set up? Does it matter what type of product (ie, downloadable vs simple, etc.?)

How are you uploading images? (ie, via the product edit/add product image, via the media library, etc.?) What type of images are they (.png, .jpg, etc)

when trying to go fix each individual featured image in the image library

What do you mean by ‘fix’ in this case? How are you fixing them?

Can you elaborate clearly on how to generate the problem you’re seeing? Can you take me through your workflow step by step? I’d like to go through it on a test site, but I need more information to do so.

Can you link us to a copy of your WooCommerce->Status report, so we can get a better context for your site/server environments?

Best,

Cena

Only simple products. Not only happening with featured images, but featured images are the most noticeable because of how it makes product listings have all uneven images (due to them not being the correct size after regen).

How are you uploading images? (ie, via the product edit/add product image, via the media library, etc.?) What type of images are they (.png, .jpg, etc)

Images are uploaded via the Add New Product/Edit Product page > Product Image & Product Gallery boxes.

“Fix” meaning regenerate again.

Just simply making changes to the image sizes that are wanted on the site, for example if you were to change to a theme that has different sized images registered, if you register your own custom sizes, etc… then regenerate. That’s all.

LiteSpeed server. PHP 7.4.3. PHP post max size 512MB. PHP time limit 300. cURL 7.84.0, OpenSSL/1.1.1d. MySQL 5.5.5-10.5.12-MariaDB-cll-lve. GZip etc on. WC DB 6.7.0.

Thank you for looking into this. Regenerate images from product A, the images from product B reset, regenerate images from B, the images from A reset. It’s like playing Mole Buster lol.

Off topic, the new style for replies here is so bad.

Hi there,

Thank you for providing details here!

In case it helps, here is the query Regenerate Thumbnails use to get featured images to regenerate.

Based on what you’re saying, I suspect that post meta is getting mixed up somehow, which Regenerate Thumbnails use to reference thumbnail image:

$featured_image_ids = $wpdb->get_results( $wpdb->prepare(
            "SELECT SQL_CALC_FOUND_ROWS meta_value AS id FROM {$wpdb->postmeta} WHERE meta_key = '_thumbnail_id' GROUP BY meta_value ORDER BY MIN(meta_id) LIMIT %d OFFSET %d",
            $per_page,
            ( $per_page * $page ) - $per_page
        ) );

Would you check your database to make sure it’s correct feature image for the regenerated thumbnails? Also, would you check and see if there’s another plugin or theme messing up with your post metas?

You can try testing this by temporarily disabling other plugins and switching to a default WordPress theme, and running regenerate thumbnail again. You can use Health Check plugin to do this plugin/theme conflict test without affecting your live site: https://www.ads-software.com/plugins/health-check/.

Let us know how that goes!
