Fixing cPanel Locale Errors

nessa • June 21, 2013

If you receive an “Internal Death” (generic cPanel speak for “something broke”) when accessing WHM and/or cPanel, the first thing you should do is check the cPanel error logs at /usr/local/cpanel/logs/error_log. You may see something like this: die [Internal Death while parsing [stdin] xxxxx] Read of CDB_File failed: Protocol error at /usr/local/cpanel/Cpanel/CPAN/Locale/Maketext.pm line 217. Cpanel::CPAN::Locale::Maketext::maketext() […]

Restoring DNS Zones on a cPanel Server

nessa • April 29, 2013

In rare situations, the DNS zones located in /var/named might disappear. We’ve heard of this happening after certain bind package updates, or simply due to administrator error.

While cPanel supports excluding sender IP addresses from these checks, some manual Exim modifications are needed to

Restoring Database Privileges

nessa • March 20, 2012

I’ve seen several cases in the last few months where database users seemingly “disappear” or privileges appear to become invalid when restoring MySQL data or an entire server from raw backups. This may commonly be attributed to a MySQL version mismatch, for example, when a server is running MySQL 5.0 and then is suddenly running

First thing, try running /scripts/fixquotas This’ll take a while depending on your current disk usage, but will usually fix the problem. If it doesn’t, make sure that

User Databases Missing from cPanel

Mark • January 14, 2011

After upgrading to cPanel 11.28, a number of our users indicated that databases were missing from their cPanels, despite the actual databases existing on the server. There are a number of things that can cause this, including corrupted Perl modules and MySQL not running, but the major cause that I’ve seen is from the new

Accessing cPanel Through A Firewall

nessa • May 23, 2010

There’s been a long-standing issue from a hosting provider’s point of where cPanel runs on abnormal ports, causing users behind firewalls to be unable to access cPanel. At first, there was cpanelproxy.net which offered (at that time) an automated script that users could install on their hosting accounts to route cPanel traffic over port 80.
