This could be due to bad file permissions, missing config.inc.php file or incorrect webmail database details. Error will look similar to the below image.

The error config.inc.php was not found can be fixed with a few easy steps on the DirectAdmin based server.

Requirements

• root access to DirectAdmin Server
• CustomBuild 2.0 installed with roundcube=yes in the options.conffile.

Procedure

1. Log in to the root user of the DirectAdmin Server.
2. Cleanup existing Roundcube files and directories.
   cd /usr/local/directadmin/custombuild
rm -f roundcubemail*
rm -rf /var/www/roundcube*
3. Clean and update CustomBuild scripts followed by building RoundCube.
   cd /usr/local/directadmin/custombuild
./build clean
./build update
./build roundcube
4. If above commands work without any error then your /var/www/html/roundcube/config/, it should contain this:
   -r--r----- 1 webapps webapps 4511 Jan 16 14:35 config.inc.php
-rw-r--r-- 1 webapps webapps 3981 Jan 2 01:30 config.inc.php.sample
-rw-r--r-- 1 webapps webapps 55612 Jan 2 01:30 defaults.inc.php

-rw-r--r-- 1 webapps webapps 2815 Jan 2 01:30 mimetypes.php
-rw------- 1 webapps webapps 50 Jan 16 14:35 my.cnf
5. If you find config.inc.php is missing in /var/www/html/roundcube/config/, you could create one from the sample file.
   First-line should look like:
   $config['db_dsnw'] = 'mysql://da_roundcube:yourdamysqlpasswordhere@localhost/da_roundcube';
   Note: You will find yourdamysqlpasswordhere in /var/www/html/roundcube/config/my.cnf file from the same directory.
