I have a user who is having trouble with a PDF export in a particular workspace. He is trying to export a single page as a PDF, and the PDF generator runs just fine - but when he tries to download the file from the link, he gets an Apache/Tomcat 403 error screen.
Initially the user was in a group that did not have the Space Export permission enabled for that space (but could still export the same page as a Word doc!). I added the permission to the group, and the same error still persists.
The user can download a PDF export of a page in a different workspace just fine.
We tried it with the browser in Incognito mode, and I tried logging in as him with my Site Admin key; the error still persists.
Any ideas?
