Hi,

I am using Zotero 5.0.34 and I have recently been getting the message 'The attached file could not be found.It may have been moved or deleted outside of Zotero, or, if the file was added on another computer, it may not yet have been synced to or from zotero.org', when I try and open certain documents.

These pdfs were working fine before but now seem to have disappeared. I cant seem to open them from the website either. However I am told that I am using 1288MB of storage.

Any thoughts?
