I just updated my jAlbum software. Previously my downloads folder which contains pdf files was working fine but now when I click on a pdf file it goes to my error page. For the life of me I can't figure out why. Any help would be appreciated here is the link to the page http://www.soulportals.com/kokeshi/KokeshiTrends/Downloads/index.html . I just checked the site files and the pdf are not being uploaded. I manually uploaded them and now the links to the files are incorrect. For instance the link for file 01.14.16 Kokeshi Trends V1 Issue 1 opens up to file 02.14.16 Kokeshi Trends V1 Issue 2.
It's telling me that the top-level tree.json file is missing or corrupt. That would be at the top of the album, at the root of your domain. Make sure that after doing any updates, even if you're just updating the Downloads folder, that you upload all of the new files, some of which will be a level above that.
I tried deleting the entire download folder and re-creating it from scratch. I still get the same issue. Also I use to be able to view the page on i.e. now It does not show any of the files. Just the text links.
Puzzling. This was definitely not working when I put the test album up, but now it is. The album hasn't been altered since then. It's as if something was getting cached, but the cache has now been cleared.
But the original poster's album is still misbehaving:
