Booking Calendar Edit/Save Clearing Data

If you look at it you are missing the session_id

It should be something like this "session_id": "1bbfdj07as68bvp3ctrboj8gs7"

So it looks like you are having a sessions problem.

If this was an upgrade then the new session are in it's own folder now.

It may be installed wrong.
