Updated onlyOffice 7.0.0 to 7.1.1
It affected login’s to the main nextcloud, users are unable to login via website.
Nextcloud and Talk app on cell-phones still works. Integrity check runs without errors, but does not return a result code.
It happens to me when I go through http. Have you tried https?
something touched with the php manager and the session folder location, all set now
