How ‘CONCATENATE_SCRIPTS’ Works
- Improved Caching: Concatenated and minified files can be more efficiently cached by browsers and content delivery networks (CDNs). This means that when a user revisits your site, the browser can use cached files, reducing the need to re-download them and improving loading times.
How to Use ‘CONCATENATE_SCRIPTS’ in WordPress
To enable or modify it in WordPress, you need to edit your wp-config.php file. Here’s how you can do it:
- Access your website’s files, either through FTP or a file manager provided by your hosting provider.
- Locate the wp-config.php file in your WordPress root directory.
- Open the wp-config.php file using a text editor or code editor of your choice.
- Look for the line that defines ‘CONCATENATE_SCRIPTS.’ It should appear as follows:
By default, ‘CONCATENATE_SCRIPTS’ is set to false, which means that concatenation and minification are disabled.

Remember to use this with caution, as some plugins and themes may not be fully compatible with it. Always test your website after making changes to ensure that everything functions correctly. If you notice any issues, consider disabling it and investigating the source of the problem.
