Hello,
I'll start with some links to documentation:
Breadcrumbs Control,
Breadcrumbs Web part Properties,
other navigation controls.
The breadcrumbs should show you the entire path depending on your actual position on the site, for example like this, when you are on the 'Team' document:
About > TeamYou mentioned the breadcrumbs do not show if you access the pages directly under the root. There might be an issue with web part settings. Could you check the following property is set like this:
Starting path: /However this is only one of things which could be causing it. If it doesn't solve the issue, please paste an export of the web part settings in here, so that I can take a look and test them. The option to export the settings is at the very bottom of the web part properties.
Regards,
Josef Dvorak
