Newsfeed & About Me links return 404 and MySites root is IIS7 splash screen

Question

I am building the SharePoint 2013 farm, and I have configured and installed both the default SharePoint site and the MySites site. For the default site I used this article: technet.microsoft.com/en-us/library/ee806885.aspx and technet.microsoft.com/en-us/library/cc263094.aspx,
and I chose the Publishing Portal template. For the MySites, I used this article: technet.microsoft.com/en-us/library/ee624362.aspx I have placed both applications in the same App Pool.
When I go to my SharePoint site, my name appears correctly in the drop down menu. When I browse to MySites root site I get the IIS7 splash screen, and when I click on the Newsfeed or About Me links from my SharePoint web site, I get a 404:
Server Error in '/' Application.
The resource cannot be found.
Description:
HTTP 404. The resource you are looking for (or one of its dependencies)
could have been removed, had its name changed, or is temporarily unavailable.
Please review the following URL and make sure that it is spelled correctly.
Requested URL: /Person.aspx
I have built and rebuilt both sites numerous times in Central Administration, synched the users profiles with Active Directory and tried changing the Default Document property in IIS. I have also rebuilt the cache several times. I am about at my wits' end,
and need to know what else I can try. Thanks.

One thing I do get relatively frequently, but cannot find an answer for is this:
