Incorrect "Save failed. Incorrect user name or password" message
This message turns up sometimes even if you have entered a correct user name and password. Seems to be associated with first log in after loading the manager. Seen on S6D site quite frequently.
This suddenly started happening again when I was trying to set up the British Relays on Monday evening. It failed about four times before I finally got it to work. Digging around it turns out that a new $keksi is generated in rg2api.php after every post request, whether it was from a manager or a normal user. So if a route gets added whilst an event is being set up the cookie gets updated on the server. When the manager posts the new event the cookies don't match. Typically this might be a 60 second window.
It really only happens for big multi-day events where lots of people are entering routes at the same time as you try to set up a new event. Especially if everyone arrives home from a British weekend and draws their route in the early evening as you try to set up the Relays.
Easy enough fix to be added in next release...
