@bismuthbullion. Thanks for posting. From examining the site, it seems that the links have two forward slashes after the word “Form”. For example, I see “http://clonbeacshs.eq.edu.au/Forms//excursion/Merlo_Coffee_Site_Tour.pdf” instead of “http://clonbeacshs.eq.edu.au/Forms/excursion/Merlo_Coffee_Site_Tour.pdf“.
If you already selected “Forms” as the Parent Folder, then place “excursion” in “Location within the Parent Folder” and not “/excursion”.
Let me know if that helps.
