Hi there – I did the same thing – but I deleted the title “Blogroll” on the Link Category page. Blogroll is the default category, so it still exists in the dropdown menus where applicable, but since I deleted the actual letters – the title “Blogroll” does not show up. Did you find a way to fix your issue? If so, your solution may help me fix mine. I am not a developer, so I do not know where to go within the wp code to fix this issue.
Thanks!
