父网站未显示在SharePoint 2013的面包屑中

您可以在这里看到，这是您可能的解决方案。替换为：

<SharePoint:SPLinkButton runat="server" NavigateUrl="~site/" id="onetidProjectPropertyTitle"><SharePoint:ProjectProperty Property="Title" runat="server" /></SharePoint:SPLinkButton>

与：

<asp:SiteMapPath
     runat="server"
     SiteMapProviders="SPSiteMapProvider,SPXmlContentMapProvider"
     RenderCurrentNodeAsLink="false"
     NodeStyle-CssClass="breadcrumbNode"
     CurrentNodeStyle-CssClass="breadcrumbCurrentNode"
     RootNodeStyle-CssClass="breadcrumbRootNode"
     HideInteriorRootNodes="true"
     SkipLinkText=""/>
