WPML compatibility

Don’t know if the author is still monitoring this support page, however, for all of you out there using WPML plugin for multilanguage, I’ve added just two simple lines to make this plugin WPML compatible. So here is the modded code for function cws_nice_search_redirect:

function cws_nice_search_redirect() {
	global $wp_rewrite;
	if ( !isset( $wp_rewrite ) || !is_object( $wp_rewrite ) || !$wp_rewrite->using_permalinks() )
		return;

	$search_base = $wp_rewrite->search_base;
	if ( is_search() && !is_admin() && strpos( $_SERVER['REQUEST_URI'], "/{$search_base}/" ) === false ) {
		if ( function_exists('icl_get_home_url') ){
			wp_redirect( icl_get_home_url()."{$search_base}/" . urlencode( get_query_var( 's' ) ) ) ;
		}else{
			wp_redirect( home_url("/{$search_base}/" . urlencode( get_query_var( 's' ) ) ) );
		}
		exit();
	}
}
