So I've been testing an upgrade of our SharePoint 2010 MySite Host to SharePoint 2013. I currently have a fresh SharePoint 2013 farm set up, and I'm restoring the 2010 content database to it using PowerShell. Everything seems to work fine after I upgrade the site collection to 2013, except the following:
Whenever I make any changes to the navigation settings for the top level site, it sets up the current navigation as if I have it set to "Structural Navigation" with "Show subsites" enabled. No matter what I change it to after that (including managed metadata) it shows all my subsites in the current navigation in alphabetical order. This is a serious problem as there are about 60 subsites
Before I make any changes, the menus appear normal. It's only after I go into
/_layouts/15/AreaNavigationSettings.aspx and click OK that it does this. Any insight on what might be causing this? I wouldn't even know where to begin to look.
