I think I’ve figured this out. My website problem is broader than I suspected, and tied to my Folder Settings - reference the topic: Can I set folder defaults for each database?
I have been setting and using a separate media folder for each database (which frankly seems logical to me, but …) and apparently each time I’ve been “fixing” this (re-entering the folder path) for each separate database by changing the folder settings, I’ve actually been breaking it for all of the others!
So now to solve this, if I understand correctly, I need to move or copy all of my media for all of my databases into one media folder, so that RM8 can find the files for its views AND to Publish Websites that correctly link to and display media?
