Overview of the issue

W3-Total-Cache is not minifying files correctly for secondary languages when WPML setting default language in directory is active.

Workaround

To enable minifying files, add following code to functions.php

function wpml_comp_2347( $data ){
	if ( did_action( 'wpml_loaded' ) ) {
		$home_url = $data['home_url'];
		if ( substr( $data['url'], 0, strlen( $home_url ) ) != $home_url ) {
			$data['home_url'] = get_option( 'home' );
		}
	}

	return $data;
}
add_filter( 'w3tc_url_to_docroot_filename', 'wpml_comp_2347', 20 );

        /**
         * Returns home url regexp
         *
         * @return string
         */
        static public function home_url_regexp() {
                $home_url = get_option('home');
                $regexp = Util_Environment::get_url_regexp( $home_url );

                return $regexp;
        }

Next steps

We understand that having to edit your functions.php is not ideal and as such, we have repeatedly tried to reach out to the W3 Total Cache team to get this issue resolved. Our current understanding is that the Pro version is compatible with WPML, but the free version is not.
