Exclude files from Defer JS

In rare cases, the option Load JavaScript deferred (in File Optimization → JavaScript Files) may conflict with a specific file.

If this option causes any problems, you may need to exclude a file from the process. You can do that by downloading, installing, and editing the following small helper plugin.

📥  Download (.zip): WP Rocket | Exclude Files from Defer JS
Developers: You can find the code for this plugin on GitHub.

Heads up! You must edit the helper plugin before use!
Remove the sample value of /wp-includes/js/jquery/jquery.masonry.min.js and insert the script path you wish to exclude. In order to exclude multiple files, copy the entire line, paste it after the first one, and edit the file path accordingly.

Tips to make this work

Remove query string

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

https://example.com/wp-content/themes/neutro/js/responsive-menu.js?ver=46e6ce

use:

$excluded_files[] = '/wp-content/themes/neutro/js/responsive-menu.js';

Remove domain name from external file URIs

For external JS files (i.e. those not hosted on your domain), remove the domain name. For example, to exclude:

https://ws.sharethis.com/button/st_insights.js?publisher=123-abc-456&product=simpleshare

use:

$excluded_files[] = '/button/st_insights.js';
