This is insane. I have tried almost everything in this thread and I’m still getting the original error after an upgrade to 5.3. I’m uploading a 216kb image in Media Library (not a post) and I get 404 error on async-upload.php in the console (yes, the file is on my server). WordPress 5.3.2. Here’s what I’ve tried:

1. Downgrading to PHP 7.3 and 7.2 (originally on 7.4)
2. Disabling every plugin
3. Installing the plugin that disables Big Image Threshold
4. Logging out/in
5. Clearing browser cache

As for the server (PHP/Apache):
post_max_size = 65M
upload_max_filesize = 65M

Not sure what else to do here. This feature is extremely broken.

I don’t know if this helps but when I inspect the rendered elements, both of them are inside a single embed wrapper and div.amazon-auto-links HTML elements.

Thanks for the quick reply. I tried the default Twenty Nineteen theme, and still had the same issue.

So I started deactivating my plugins, one by one, until only your plugin was left. It’s still doing it. I even disabled Akisment and WP Super Cache. No change.

I have had issues before where some plugins cause problems even when they’re deactivated, but I really don’t want to start deleting my plugins and lose their settings when I don’t even know which one it might be.

Thanks for posting this! The same problem was driving me insane too. I never would have thought to change the name to a capital ‘L’.

This is definitely a bug in WordPress 2.5, because every other web app I have running on this machine uses “localhost” and it connects to the MySQL server just fine.

Never mind, it just started working spontaneously today.
