Missing reference folder
I recently sent an article to a collaborator and on its return Zotero no longer recognises the references in the article. Moreover, the folder for this particular project is now empty. The collaborator used Word on a PC, whereas I used Word on a Mac. Other than that I can't think why this has occurred. It is very frustrating and if anyone has any tips I would be very appreciative. Thanks
A collection missing from your Zotero library wouldn't be related to this at all. That would happen if you deleted a collection by mistake. If you just did so within the last day, you can try to restore from one of your last automatic backups.
