AJAX Thumbnail Rebuild Reviews
Still Works Great!
With over 4K images on my site, it’s impossible to get “Regenerate Thumbnails” in Woocommerce to complete. This takes care of it in a couple hours without taking a break. Thank you! Running WordP
Seems to be a dead plugin
No replies to support queries for over a year so it seems like a dead plugin. hopefully you backup your site before trying this.
This should be in Core
This is a great plugin, easy to use and it should be in Core in some way or form. It’s ridiculous that Woo does automatic thumbnail regeneration, but WP Core doesn’t. Thanks for this.
