That fixed it, sorta. For now I'm leaving it in standalone mode.
One other problem I've noticed: If I go to the daily page, the Other Years drop down defaults to 2018. That's fine for a start. If I change to another year, the data is displayed for that year. But, the drop down is still on 2018, not the selected year. This is a problem because if I click on another button (say rain instead of temperature), I get the data from 2018 and have to re-select the other year again.
The sorta comes in because the detail page completely takes over the displayed web page, hiding/replacing my standard web page.
