Support » Plugin: Auto Post Thumbnail » [Plugin: Auto Post Thumbnail] WordPress 3.4: Stopped Working, Thumbnails Missing

  • Resolved rowsdowr

    (@rowsdowr)


    After upgrading to WordPress 3.4 I noticed that most of my Featured Image thumbnails were missing. It seems that thumbnails I had set manually were still displayed, but ones that were generated by this plugin wouldn’t show up anymore.

    The missing thumbnails are gone from the front end and are no longer set as Featured Image on the Edit Post screen. They are still listed in the gallery but the their preview images are blank.

    When creating new posts, this plugin doesn’t generate thumbnails automatically anymore.

    I looked around in the MYSQL database and noticed that thumbnails generated by this plugin don’t have a _wp_attached_file entry in the _postmeta table. Manually set thumbnails, which still work, have _wp_attached_file set to their specific image URL. Maybe this has something to do with it?

    Thanks

    @misthero or @gothickmatt , is there an SQL query to bulk delete all “attachments” from posts. I have to many posts, it will take ages to do one by one

    @asialove Your solution worked perfectly!! But i already deleted a lot of images in my folder, so now the featured images shows up as not found, do you know any query to bulk remove all attachments from posts? so i can generate them from scratch.

    There’s no way I’m editing WordPress core files for something that looks like it can be solved by changing one line in the plugin 🙂

    oomskaap, did you try the solution in my last post?

    oomskaap, do not edit your database,, just leave it there,
    upload the images by ftp again to the folders..

    @asianlove yes i did, and it worked perfectly. But unforunately before i tried it, i deleted all the generated thumbnails in my upload folder. So the old featured images are still “stuck” in there with a not found logo. Which means i have to click “remove feautured image” on all my post. But i have over 1000. Any bulk way to do it once ?

    oomskaap, u need an sql-query smth like this:

    DELETE FROM wp_postmeta WHERE meta_key = '_thumbnail_id';

    but I didn’t test it and do not take any responsibility for any troubles, you understand…

    Auto update old posts without deleting after you applied my previous fix or the gothickmatt one you can use this modded version.

    do a backup of your database just in case

    1. upload to plugin folder
    2. disable auto-post-thumbnail or auto featured images
    3. enable this
    4. go to the option page and press the red button
    5. wait.
    6. wait and do not refresh the page, depending on the number of posts it can be very slow, in my case it took 20 minutes for 4567 posts.

    this will process all your post and regenate working thumbnails only for videos. be careful it will generate a thumbnail even if it already exists, this is why it works, it will update the broken thumbnails, be patinent, the process is slow.

    When finished DISABLE this modded version and reenable your version.

    have fun!

    try this to check if the “feature image” value is still stored in your database

    SELECT * FROM wp_postmeta WHERE meta_value like ‘%jpg%’and meta_key=’_wp_attachment_metadata’

    Good for you!

    People: Never, ever, edit core WordPress files.

    @asialove: Please stop advising people to edit core. If there’s an issue with the plugin, fix it, Don’t change core.

    @danstudio , worked like a charm! thanks to everyone in this thread. My site is up and working again with thumbnails restored.

    oomskaap, great!

    I’ve came to this solution just an hour ago while reading about SQL queries )) Just wanted to clear thumbnail cache. I’m happy my investigation wasn’t useless ))

    I went with misthero’s suggestion and added

    update_attached_file( $thumb_id, $new_file );

    to auto-post-thumbnail.php as I too didn’t want to mess with core files. I then used another plug-in to removed all featured images from old posts, then re-generate thumbnails using the Auto Post Thumbnails plugin. Everything is back to normal now.

    Thank you misthero! 🙂

    where i will put this code plzz??????
    DELETE FROM wp_postmeta WHERE meta_key = ‘_thumbnail_id’;
