sar-exclude-gf-from-rocket-loader.php

<?php
// NOTE: The code to copy/paste starts below this line

// Don't apply Rocket Loader to scripts needed by Gravity Forms
add_filter( 'script_loader_tag', 'sar_gf_rocket_loader_safe', 10, 3 );
function sar_gf_rocket_loader_safe( $tag, $handle, $src ){
	if ( strpos( $handle, 'gform' ) !== false || 'plupload-all' === $handle ) {
		return str_replace( "src='", "data-cfasync='false' src='", $tag );
	} else {
		return $tag;
	}
}

This isn't working on my site, is there a new method to fix gforms to make it compatible with rocket loader?
