Tips to make this work

Excluding multiple files

Wildcards don't work here. Each exclusion must be added with a new line. For example:

$excluded_files[] = '/wp-content/plugins/plugin-name/filename1.css';
$excluded_files[] = '/wp-content/plugins/plugin-name/filename2.css';
$excluded_files[] = '/wp-content/plugins/plugin-name/filename3.css';

Remove query string

Remove any query string following the .css extension. For example, to exclude:

https://example.com/wp-content/themes/neutro/style.css?ver=1.2.5

use:

/wp-content/themes/neutro/style.css

Excluding externally hosted files

Use the filepath following the domain name to exclude files not hosted on your own domain. For example, to exclude:

https://cloud.typography.com/6907774/6146531/css/fonts.css

Use:

/6907774/6146531/css/fonts.css
