RSS Feed Not Working! HELP

My feed stopped working several weeks ago.. I’ve been trying to fix with Feedburner but now I realise the RSS from site is wrong. I think. Its driving me nuts.

I took 2 years to get 800 subscribers and no I can’t reach them
The blog is https://heartofwisdom.com/blog

Here is my meta code

<ul>
		<?php wp_register(); ?>

<li><?php wp_loginout(); ?></li>
<li><a>" title="<?php _e('Syndicate this site using RSS'); ?>"><?php _e('RSS'); ?></a></li>
<li><a>" title="<?php _e('The latest comments to all posts in RSS'); ?>"><?php _e('Comments RSS'); ?></a></li>
<li><a href="https://validator.w3.org/check/referer">"><?php _e('Valid XHTML'); ?></a></li>
<li><a href="https://gmpg.org/xfn/">XFN</a></li>
<li><a href="https://www.ads-software.com/">">WP</a></li>
		<?php wp_meta(); ?>
	</ul>

ANY help greatly appreciated.
