When reopening a document, I always get "You do not have permission to access this pad"

[fodor0205]

Steps to reproduce:
1, Log in with an owncube.com account
2, Allow the request
3, Create a new document
4, Edit a few characters
5, Close the document
6. Reopen the main site (with document links)
7. Open the previously edited document
8, It gives "You do not have permission to access this pad" error

I've deleted the whole folder structure in the owncube.com interface, logged in again, it created the folders, but the same error appears.
