The above warning might show up each time when any of cPanel services are used.
This is because cPanel / Webmail is configured to work by the server’s shared / self-signed SSL
This is not a security problem and you can safely disregard it.
To get around this issue though, either accept the certificates and tell your browser to ignore the warnings, or purchase an SSL certificate that is mapped to your main server hostname and then assign that certificate to all of the cPanel services.
When trying to upgrade MySQL server from WHM or via script,
# /scripts/mysqlup –force,
Do you face the below error message?
-bash-3.00# /scripts/mysqlup –force
Failed to download http://httpupdate.cpanel.net/RPM01/centos/unknown/i386/MySQL-server-5.1.63-0.i386.rpm
Failed to install mysql51.
Reason : In this particular scenario, if you analyze the logs, we can find that there is some issue with the rpm file to be fetched. If you observe the link from which the update is trying to fetch the required rpms we can see that the link actually doesnt point to a valid page. If you manually try to access the above link via a web-browser this results in ‘Not Found’. In the link, you can see a keyword ‘unknown’ in the space allocated for rpm distribution version.
Fix : Change the wrongly specified rpm_dist_version.
Change it from
/var/cpanel/sysinfo.config. Change the “rpm_dist_ver” to point
the current centOS version, that is 4 or 5.
Then proceed with upgrading process.
This can be an issue not only during MySQL upgrade, rather when any upgrade relating
with the use of RPM’s is specified. ( eg : Pure-FTPd )
After installing ionCube loader via EasyApache or using the script,
/scripts/phpextensionmgr install IonCubeLoader
Do you face any issues with PHP?
Do you get the following error message when you tried to check the version of PHP using the command,
# php -V :
The ionCube PHP Loader is disabled because of startup problems. Segmentation fault
Reason : Usually happens due to double entries in the php.ini file (/usr/lib/php.ini)
Remove one line or comment one line,
Can remove ionCube by running the following script :
# /scripts/phpextensionmgr uninstall IonCubeLoader
Do you want to remove fantastico and its services from your server?
Unfortunately, no easy method to remove it from front-end.
SSH to the server and issue the following commands.
# rm -rf /var/netenberg/
# rm -rf /usr/local/cpanel/whostmgr/docroot/cgi/fantastico/
# rm -rf /usr/local/cpanel/3rdparty/fantastico*
# rm -rf /usr/local/cpanel/base/frontend/*/fantastico
# rm -f /usr/local/cpanel/base/frontend/x/cells/fantastico.html
# rm -f /usr/local/cpanel/whostmgr/docroot/cgi/addon_fantastico.cgi
After removing fantastico from the server, does any of the cPanel accounts shows the fantastico icon ?
You can remove it by doing the following :
From the backend, go to
and delete the line corresponding to “Fantastico_De_Luxe”
WHM->Packages->Feature Manager, remove the fantastico check box
Do you happen to get an internal error page when trying to access csf via WHM?
Reason : Perl scripts used by csf seems to be oudated.
Fix this issue by updating the concerned csf scripts.
# curl -s configserver.com/free/csupdate|perl
A weird situation is when you can see the databases, its tables and so on from phpmyadmin of the concerned cPanel account, but is actually found missing under the ‘Databases’ section.
Reason : This issue occurs due to the lack of mapping of databases
Error faced : Waiting for ftpserver to restart..finished.

Reason : Pure-ftpd service doesn’t work with CallUploadScript set to yes in
/etc/pure-ftpd.conf file. That is because the pure-uploadscript service is not getting
started while restarting the pure-ftpd service.
# /usr/sbin/pure-uploadscript -B -r /etc/pure-ftpd.conf
Then restart the pure-ftpd service —
# /etc/init.d/pure-ftpd restart
Ever came across a situation in which /root/.cpanel/comet consumes considerable amount of disk space?
Reason : This issue happens when high number of emails are in the mail queue manager which can occur when spamming is carried out in the server.
Manually purging the files would be an effort-consuming task.
Clear the comet directory as shown :
This is a common issue with cPanel when trying to update
The complete error message :
“fatal: Your RPM database appears unstable. It is not possible at the moment to install a simple RPM”
Reason : RPM database gets corrupted over a while, hence preventing cP from updating.
# mkdir /root/old_rpm_dbs/
# mv /var/lib/rpm/__db* /root/old_rpm_dbs/
# rpm --rebuilddb ( rebuilds the RPM database )
# /scripts/upcp ( cPanel update )
