I had a site working just fine with Drupal 6.16. Then I updated to 6.17 (and updated all of the modules), and all of a sudden the uploaded files were all generating Access Denied errors.
If I switch the file system to Public, it all works fine (what I did as a workaround).
I tried a file compare to see what changed between editions and also searched all of the modules for possible places that the access denied function is called. I even changed file.inc to ignore other modules file_download methods temporarily with no luck.
There's no special access control modules installed.
Does anyone have any other ideas where to look to see where this could be bugged?
Everything else works fine. Just the "uploaded files" that get Drupal's Access Denied error.
I didn't change the settings.php or the .htaccess file.
