Installing subscribe to comments in origami

Hi

I’m trying to integrate ?subscribe to comments reloaded” in origami theme. It does not work. The instruction says:
If you don’t see the checkbox to subscribe, you will have to manually edit your template, and add <?php if (function_exists(‘subscribe_reloaded_show’)) subscribe_reloaded_show(); ?> somewhere in your comments.php

Also I tried to realize https://behstant.com/subscribe-reloaded/realMgnPage.php

Is there a possibility to set ALL fonts to white?

Can you help me?
