Installer Stylesheet Not Using a Correct MIME Type

[timnolte]

Looking at the browser console I'm seeing a failure to load the installer.css file since it's not using a proper MIME type.

Refused to apply style from 'https://www.timnolte.com/wp-content/plugins/indieweb/assets/installer.css?ver=5.6.2' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Are you sure you run the latest version? The file returns a 404 issue, because we do no longer use the mentioned URL, we changed it to static/css/installer.css: https://github.com/indieweb/wordpress-indieweb/blob/trunk/includes/class-plugin-installer.php#L389

Maybe a caching problem?

Also, it says ver=5.6.2 which is strange, as the plugin is at version 3.4.6

It is the WordPress version.

Yes, but the code uses the plugin version

Maybe an issue with the call, so it falls back to the WP version?
