Account Creation Failed
While creating an account via WHM, you may get an error stating that, cannot create new user.
You can check the cPanel logs for the error.
tail -f /usr/local/cpanel/logs/error_log
Sometimes, you may get the following error.
vipw lockfile (/etc/ptmp) is present!
This means that the “useradd” is locked. You will not be able to add new users unless you remove the following file.
You can also confirm it by executing the useradd command in the konsole. You will receive an error message stating the above.
Check if this file is present.
ls -l /etc/ptmp
/etc/ptmp >> This has a temporary copy of the password file. This file can be removed.
rm -f /etc/ptmp
Cpanel WHM: License expired error
If “License expired” error is encountered while accessing the cpanel/whm, it can be fixed by following below mentioned steps:
1. Check whether the license is expired.
This is the most obvious cause and simple to verify. Access the URL ‘http://verify.cpanel.net/’ and check the IP of the server.
2. If it is “active”, Run the following command:
$ /usr/local/cpanel/cpkeyclt
This should promptly return to the command line with no messages. If it takes a while, then there is likely a connectivity issue between your server and the licensing server.
3. In that case, check whether the firewall is blocking connections to the licensing server.
Verify that port 2089 TCP outgoing traffic is allowed in the firewall rules.
4. If you’re not sure that your firewall is properly configured, then the best thing to do is temporarily flush your firewall rules. Before flushing the firewall rules, you need to save the firewall rules enabled in the server.
$ /etc/init.d/iptables save
After that you can flush your firewall rules using the command
MySQL Socket Error in phpMyAdmin
While accessing phpMyAdmin, you may get the following error.
#2002 - The server is not responding (or the local MySQL server’s socket is not correctly configured)
This is due to the missing socket file in the location /tmp.
The socket path which is specified in the phpMyAdmin configuration file is /tmp/mysql.sock.
$ vi /usr/local/cpanel/base/3rdparty/phpMyAdmin/config.inc.php
cfg['Server']['socket'] = ‘/tmp/mysql.sock’;
If mysql.sock is missing in /tmp, then create a link to the mysql.sock file in /var/lib/mysql.
$ ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
There is also another fix for this issue.
1. Open the phpMyadmin config file “config.inc.php”.
vi /usr/local/cpanel/base/3rdparty/phpMyAdmin/config.inc.php
2.Locate the line:
$cfg['Servers'][$i]['host'] = ‘localhost’;
3.Replace ‘localhost’ with ‘127.0.0.1′ and save.
$cfg['Servers'][$i]['host'] = ‘127.0.0.1′;
This will also fix the issue.

Edit the configuration files
using your text editor edit db.inc.php
Find:
$rcmail_config[’db_dsnw’] = ‘mysql://roundcube:pass@localhost/roundcubemail’;
Replace with:
$rcmail_config[’db_dsnw’] = ‘mysql://root:rootpass@localhost/roundcube’;
#vi main.inc.php

cd /usr/local/cpanel/base/roundcube/skins/default/images/
cp roundcube_logo.png /usr/local/cpanel/base/frontend/x/images/roundcube_logo.png
cp roundcube_logo.png /usr/local/cpanel/base/webmail/x/images/roundcube_logo.png
wget http://www.yourserverguide.com/Files/HGpatch-roundcube-1.0BETA2.1
patch -p0 < HGpatch-roundcube-1.0BETA2.1
