can't save shared document if a second user has opened it too.

[redglobuli]

Describe the bug I shared a document and if only me is opening it i can save it just fine. As soon i open with another user at the same time i get an error message like "document can't be saved. check your permissions."

To Reproduce Steps to reproduce the behavior:

1. share a document
2. open it with 2 different users
3. edit something
4. try to save

Expected behavior I expected to be able to save editing a document with multiple users

Does this still occur for you with >27.0.1 Server?

Also, is the behavior different witjh newly created files versus existing ones?
