Scott- Thanks so much! First for jumping in and helping so quickly, and second, for actually knowing how to fix the problem. I’m not all familiar what the permalinks page actually does within WordPress… I am learning WordPress as fast as I can (been developing software for over 40 years), but as usual, with my feet to the fire.
In any case, just re-saving the settings on that page worked. Can you give a short synopsis of what that did under the covers so I add it to my learning bank? Just looking at what it says doesn’t give me any real clues as to why that fixed things.
