Hi All,
 Iam getting Databse error while configuring.Please help to solve this issue.
Check config files
main.inc.php:  OK
db.inc.php:  OK
Check if directories are writable
RoundCube may need to write/save files into these directories
temp/:  OK
logs/:  OK
Check configured database settings
DSN (write):  NOT OK(MDB2 Error: not found)
Make sure that the configured database exists and that the user has write privileges
DSN: mysql://roundcube:pass@localhost/roundcubemail
Test SMTP settings
Server: PHP mail()

Test IMAP configuration

Connecting to localhost...
IMAP connect:  NOT OK(Could not connect to localhost at port 143: Connection refused)
			
			
			
				It look like it can find the database, double check that the database exist and that it's attached database user has full write privileges.
