Hi Ben,
This is coming from the breadcrumbs module(http://take.ms/xypxL). I have helped you unpublished this module it so it no longer shows at the bottom of the site. Double check and let us know how it goes.

EDIT: For the "Back to top" link, this is actually generated by the template and there's no setting to remove this. Perhaps you can apply the custom css below and see how it goes?

body.com_easysocial.view-login .footer a#back-top {

	display: none !important;

}

Do note that is only hides the link on EasySocial login page.

That's great thank you Raymond.

What about "Back to top" link on the home page before signing in?

Hey Ben,
I have added the response for the "Back to top" link in my previous reply.

Ok so if i change this and then i update my easysocial when a new version comes out, would it bring that text back?

Hey Ben,
You can add the custom css codes per this documentation. The changes in the custom css files is protected from future updates.
For the custom css codes supplied above, do note that this is catered to your current template. So if you change your site template in the future, those codes may no longer work.
