# Thumbnails Not (Re)generating

 * Many of my FooGallery thumbnails are no longer displaying across more than 50
   galleries. Console shows 404 errors for image URLs like:
 * `https://dungeonsandtoast.com/wp-content/uploads/cache/remote/dungeonsandtoast-
   com/4232066505.jpg`
 * The actual original images still exist and load fine at their normal paths (e.
   g. `/wp-content/uploads/2024/07/Dog.jpg`). It appears FooGallery is generating/
   storing thumbnail URLs that point into a `wp-content/uploads/cache/remote/dungeonsandtoast-
   com/` folder, and many of the expected files in that folder are missing (only
   ~262 files present, but far more galleries/images reference paths in that folder).
 * **What I’ve tried:**
    - Regenerated thumbnails (via Regenerate Thumbnails plugin) for affected images—
      reported success, but the gallery’s displayed URL didn’t change at all, still
      pointing to the same dead `cache/remote/...` path.
    - Cleared FooGallery’s “Gallery HTML Cache,” “CSS Optimization Cache,” and “
      Thumbnail Cache” (multiple times) — no change.
    - Ran FooGallery’s “Thumbnail Generation Test” — reported successful.
    - Confirmed Thumbnail Engine is set to Default (not ShortPixel), and Imagick/
      GD are both supported and active.
    - Toggled the global “Use Original Thumbnails” setting — saves fine, but doesn’t
      change the broken images’ output.
    - Tested the per-gallery “Force original thumbnails” checkbox on one gallery—**
      this does fix the display**, switching the image to its standard WordPress
      thumbnail. However, this isn’t a practical fix across ~60 galleries (and I
      don[t want to render that many large images) per page.
    - Searched `wp_postmeta` and `wp_options` for `cache/remote` and the broken 
      filenames — no matches found, so the reference doesn’t appear to be stored
      as plain text in those tables (possibly JSON-encoded, in a different table,
      or generated dynamically).
    - Renamed `advanced-cache.php` and disabled `WP_CACHE` in `wp-config.php` — 
      no change.
    - Suspected Media Cleaner (Pro) may have deleted files from the `cache/remote/
      dungeonsandtoast-com/` folder as “unused,” but the affected file is simply
      absent from that folder entirely (never generated, or deleted with no record).
 * **Question:** Where/how does FooGallery store the reference to this `cache/remote/
   dungeonsandtoast-com/` thumbnail path for a given gallery image, and is there
   a way to bulk-clear/regenerate these references across all galleries so they 
   fall back to standard thumbnail generation (without manually checking “Force 
   original thumbnails” on each of 60 galleries)?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fthumbnails-not-regenerating%2F%3Foutput_format%3Dmd&locale=en_US)

 * hi [@loni2shoes](https://wordpress.org/support/users/loni2shoes/)
 * We made some changes recently in the thumb generation logic, which could be causing
   this problem for you. Under Settings -> General, is your WordPress Address (URL)
   set to anything other than [https://dungeonsandtoast.com](https://dungeonsandtoast.com)?
   Because that is probably why it is determining that your thumbs should be loaded
   from remote instead of local.
 * In the meantime, I am going to build in more guardrails to prevent this from 
   happening.
 * Sorry for the inconvenience caused, and hopefully we can get this sorted for 
   you asap.
