Without using any WordPress plugin you can easily remove query strings from your assets with a few lines of code. Simply add the following to your WordPress theme functions.php file.
/**
* Remove query string from static resources.
*/
function remove_query_strings() {
// Check if admin backend.
if( ! is_admin() ) {
add_filter( 'script_loader_src', 'remove_query_strings_version', 20 ); // Remove query string of JS static resources
add_filter( 'style_loader_src', 'remove_query_strings_version', 20 ); // Remove query string of CSS static resources
}
}
/**
* Hooks for splitting url to query and return only the resources static url.
*/
function remove_query_strings_version( $src ){
$arr = preg_split( "/(&ver|\?ver)/", $src );
return $arr[0];
}
add_action( 'init', 'remove_query_strings' );
