High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 4.5.33, well behind 6.8.

Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    Works perfectly, the only plugin with regenerate specific thumbnails on post editor. Note to competitors:was is that hard to think about it? Note to author: Great work, you can make it king if you can add feature regenerate only broken image sizes Saved me half my life in a 100k media library.

    I’ve tried everything they say to do and this plugin unfortunately just does not seem to work with 4.7.4.

    Doesnt have 4.4.1 bulk generation support. But you can generate thumbnails one by one.

    We had to change a few sizes and regenerate many images in a short time, excellent plugin. Will improve the notification to terminate the regeneration process of the thumbnails for the user log is reached as to distract. Thanks LOOR Lab Colombia

    This one works with 4.0. SPREAD the word. You could show more specific messages during errors, but I can live with that.

    I tried 3 different regeneration plugins, including 2 of the top downloaded and top rated plugins. Out of the three, this is the only one that successfully regenerated all of my images. On top of that, it successfully fixed all of the dead images that the other 2 plugins created when they failed to regenerate/resize specific images for unknown reasons. This plugin fixed the images on my site and did it the right way. THANK YOU!!!

    This was the only regenerate thumbnail plugin I found that worked! Also love that you can be very specific and only do a range of images, however mine worked when I did all of them at once. Thank you!
