Not able to view Accounts in WHM List Accounts

There are many reasons for an active account to disappear from WHM List Accounts.

Assuming the disappeared account as www.r6host.com with username ‘serveruk’, you should check following entries on the server:

1) Check for the VirtualHost entry for the domain in /usr/local/apache/conf/httpd.conf file. If the VirtualHost entry is missing, add it.

2) Check the entry for the domain in /var/cpanel/users/serveruk. If the entry domain the domain appears like XDNS=r6host.com, change it to DNS=r6host.com.

3) Check the entry for the domain in /etc/userdomains & /etc/trueuserdomains.

4) If the domain is not visible in only reseller WHM, you should check the entry in /etc/trueuserowners.

SuPHP Settings - Softaculous

Overview

These settings need to be changed if you have suPHP enabled on your server. It tells Softaculous to set the correct permissions for writable files and folders.

Go to settings, edit the CHMOD Files to 0644 and CHMOD Directories to 0755 (shown in the figure) and click edit settings.

Config File Settings

If you are running suPHP and would like CONFIG files to be more secure than set the CHMOD config files to the permission you wish to set. e.g. 0600 will make it readable only to the user and no one else.
