Thumbnails are not generated (or regenerated)

    Most picture will not generate thumbnails, whatever I try. Regenerate does often not work either. I get the message that the generation was successful, but no luck. Please see screenshot.
    I am using Real Thumbnail Generator, but also wit other plugin it does not work. I changed PHP from 7.4 to 8, but still the issue remains.
    The pictures are uploaded via another tool, ‘automatic’. When manually adding a JPG it does work, when I am in the ‘more’ tools.

    And when I change the scale with 1 pixel and update, the it does get generated!!

    Hey @luiindezon !

    > The pictures are uploaded via another tool, ‘automatic’. When manually adding a JPG it does work, when I am in the ‘more’ tools.

    It looks like the plugin / tool you mentioned, does not use the WordPress core standard functionality to upload files to the media library. Therefore, Real Thumbnail Generator (or another regeneration plugin) cannot read metadata (which is generated through https://developer.www.ads-software.com/reference/functions/wp_generate_attachment_metadata/) which is needed for the regeneration process.

    ok, clear, thanks Matthias. Do you think there is a solution?

    Hi again!

    As you wrote in your initial request, you are using another plugin to upload files (“The pictures are uploaded via another tool”). I think you need to contact them and ask if they can use the WordPress core upload functionality to generate file metadata.
