So, the system pops up a notification - but it disappears in about 2 seconds. I managed to do a screen capture as it was having difficulty with my email configuration.
However, it was still failing to reset the password. In the logs I see
seahub.auth.views:341 password_reset timestamp out of range for platform time_t
Doing a web search, there are several hits but nothing for seafile. I have yet to track down the code that is failing.
