The Top Link bar is showing however I do not have the Top Link Bar option under Look and Feel within Site Settings. What is needed to restore the option to the settings menu to allow for changes to be made to the Top Link bar?
Thanks
The Top Link Bar option is only available when you have the publishing features deactivated (SharePoint Server Publishing Infrastructure feature under Site Collection Features to be specific).
For sites that have publishing features turned on, you would see Navigation instead.
Reference: Customize the top link bar.
