While trying to access phpmyadmin on WHM if you get following error:
[wpfmb type=’error’ theme=2]Existing configuration file (./config.inc.php) is not readable.[/wpfmb]
Do the following steps to resolve:
Login to the server as root.
Go to the directory /usr/local/cpanel/base/3rdparty/phpMyAdmin.
Check the ownership of the file. Check if the ownership of the file is assigned to root:cpanelphpmyadmin.
If the ownership is not correc set it to root:cpanelphpmyadmin.
chown root:cpanelphpmyadmin config.inc.php
Just restart the cpanel and mysql service on the server.
/scripts/restartsrv cpanel /scripts/restartsrv mysql
