For some reason this error is coming up with the "Fix It" button and will not fix this issue. I went ahead and deleted the line it's suggesting is causing the issue and still no luck. I was using this theme on the previous plugin version as well without an issue. Now 126.96.36.199 seems to be causing this.
Your theme contains a meta description, which blocks WordPress SEO from working properly, please delete the following line, or press fix it:
<meta name="description" content="<?php bloginfo( 'description' ); ?>" />
