how do you delete that blogroll?

Depending on your set up sidebar.php I would think.

Probably in the sidebar – it is called by a template tag
see https://codex.www.ads-software.com/Template_Tags
the Links Manager tags section

Those links that come “built-in” with WP you can delete by going to the Manage Links section in the admin panel

Have you looked under Links in your wp-admin

Thanks Dave, that did it!

When i go into my admin control panel and attempt to delete the blogroll i get this error message:

Can’t delete the Blogroll link category: this is the default one

But you can rename and/or add other (your) links into that category.

I just removed all the links from the blogroll and then it disappears. And then made my own links section.
