Prevent showing full path

[bichumo]

Hi,

How to prevent showing this when login is not accepted and leave just the message that roundcube pops up?:

IMAP Error: Authentication for user@domain.tld failed (LOGIN): "a001 NO Authentication failed."

Warning: Cannot modify header information - headers already sent in /path/roundcube/program/include/rcube_shared.inc on line 154

Thanks for any offers.

In config/main.inc.php find:

$rcmail_config['debug_level'] = 1;

and change 1 to 4.

Thanks it helped. I've changed it from 4 to 1.
