Hi,
I’m on the Handy theme and would like to remove the RSS Blog Feed from the blog posts page (because it’s not working). When I click on it, I get a source page that shows the details for all the blog posts. Can someone tell me how I can do this?
Thanks!
You will need to put in below code to the last line of your under your theme.css
by going to your store admin > Online Store > Themes > Actions > Edit code > Assets folder.

.section-blog .blog-rss-feed a {display: none !important;}
Please give it a try and let me know how it goes.
Sorry you are facing this issue, it would be my pleasure to help you.
