Great and helpful response. I was able to get the menu to display. The issues with the index.php showing are the usual Joomla related issues with configuring SEF/HTACCESS and such which I'm working on separately. I'm curious about some HTML noise though in some pages such as:
https://cruiseaficionados.com/portal/index.php/cruise-news-2/amp

There seems to be some doubling of the author and shome HTML code bleeding into the presentation. Any thoughts on what I need to adjust?

No rush, given the holiday.
