Hello, I don't know what's happen, maybe I made a mistake, How can fix this problem ? When I want to access via the browser https://...../webmail I have this error. DATABASE ERROR: CONNECTION FAILED! Unable to connect to the database! Please contact your server-administrator. Thank you
Check the database is running. If it worked previously, what has been done between when it was working and now? Since you revealn nothing about your setup, no more definitive advice possible.
