I have been tasked with changing a sub site name in our SharePoint 2010. The name change was easy, however the top link bar still links to the incorrect name. So I then went to "Top link bar" under "Look and Feel", however the links are different to that of the top link bar. I have attempted to visit look and feel from the main site and all sub sites and I cannot find the main link bar.
I got there in the end with help from Benny
My different menus were due to a predecessor creating a custom SiteMapProvider for one of the Master pages. This Provider was declared in the web.config in the route of the site. The actual sitemap however was stored on a different drive in the ControlTemplates location...
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\1033
When I editted the top links it would revert to the built in provider and edit links as normal so nothing ever changed.
Morale of the story:- Get sharepoint designer and check the actual xml to see what SiteMapProvider your SiteMapDataSource is using in the Master page.
