Hi there! You should look first at the error log file located at components/com_roundcube/logs/error and see there if you have any related messages!Feel free to also attach it here!
Second, the roundcube database details are stored in the components/com_roundcube/config/db.inc.php file and they are based on the Joomla main ones, you should read there a line like this
| Code: |
$rcmail_config['db_dsnw'] = 'mysql://'.$mosConfig_user.':'.$mosConfig_password.'@
'.$mosConfig_host.'/'.$mosConfig_db;
|
Let me know if you still have issues! Regards, Ovidiu
