Hi,
not sure what is happening from your side, but from our side this working fine.
For example, before you added portfolio page “Sun in the sky” and now you add new portfolio page “New road” and for “New road” you set “People” category, but for “Sun in the sky” page, you added “Nature” category before and now also “People” category. Then when you go to see your page at Portfolio section, you will see “New road” with “People” category, but you will also see “Sun in the sky” with this two categories: “People” and “Nature”. “Sun in the sky” page will be display because it contains “People” category.
We also can’t access to your WordPress because we again see same error:
