Hi there @matthew6, thanks for reaching out to us here!
So that we can try isolate the issue, can you close the desktop app and try saving content the same way as before? You can close the app by:
Clicking the Dropbox icon in your menu bar.
Click the profile pic/initials icon in the top right of the window.
Choose "Quit Dropbox".
Could you also send me a screenshot of the error message that you're getting?
It sounds like the issue might be due to permissions on your folders, which Dropbox can't change, so the screenshot will be helpful to see if the error is given by the OS or Dropbox.
Let me know what you find and we'll go from there - thanks!
