We have an issue where all images from the media library display fine. But PDFs stored in the media library download with 0 bytes.
We've tracked this down to an issue somewhere in the Multisites configuration as with a single site the PDF downloads without any issues. However with multiples sites configured it fails to find the PDF in the media cache and returns a zero byte file.
Is this a bug or do we need to configure something to resolve this?
