saintmoz on "[Plugin: WP Super Cache] Plugin still affecting my feed"

I have disabled then deleted this plugin as it conflicted with my podcasting plugin. But it is still affecting my feed http://tableforate.com/feed/podcast and if you scroll to the bottom you can see

` <!-- Dynamic page generated in 0.839 seconds. -->
<!--
Cached page generated by WP-Super-Cache on 2015-04-09 10:24:49
--></blockquote>` How do I delete this because it seems to be affecting how the feed works with itunes.
