The DataSourceID of 'TopNavigationMenuV4' must be the ID of a control of type IHierarchicalDataSource. A control with ID 'topSiteMap' could not be found.
Could some one help me to fix the above error? I am getting this error when I search for an item. I have checked the Crawl service and it is fine. I have checked the web.config for any errors or extra characters. But there is nothing wrong with the web.config. I have also checked the permissions. This is also fine.
