FleetSSL (free with cPanel)

FleetSSL is included with your cPanel license. After installing the cPanel licensing system, activate FleetSSL with the following:

LicenseComPkCP -fleetssl

WHMCS

WHMCS License File

Keep your WHMCS instance in sync with the latest License.com.pk license file by replacing the License.php file in your installation.

The WHMCS license file is periodically updated. Always compare the update date against your installed version.

The WHMCS License file was updated on: 2025/05/19

Download

Download WHMCSLicense.zip

Replace file at

YOUR-WHMCS-PATH/vendor/whmcs/whmcs-foundation/lib/License.php

For the latest WHMCS installation file itself (not only the license file), please contact License.com.pk support.

Verification

Verify Installation Output

After running the installer, check the summary output to confirm that the license status is OK and the expiry date matches your order.

A successful installation will show output similar to the example below. IP, hostname, kernel version and dates will reflect your actual server.

Troubleshooting

License Troubleshoot

Common commands to fix licensing issues for cPanel when you see error 500, invalid license file, PostgreSQL login failures, or missing locale files.

cPanel error 500 / invalid license file

If you see HTTP 500, invalid license, or "Incorrect authority delivering the license" errors, remove any previous license and run the fix command:

LicenseComPkCP -fix

This command checks common cPanel licensing issues and attempts to correct them automatically.

cPanel PostgreSQL login failed

If PostgreSQL is installed and clients see login failed in cPanel, run:

LicenseComPkCP -pgsql

This will configure PostgreSQL and fix common authentication and configuration issues.

cPanel locale files

To install or repair cPanel locale files, run:

LicenseComPkCP -locale

After running this command, choose your desired locale from the list in the terminal.

This troubleshoot document will be updated as new scenarios are discovered.

FAQ

Frequently Asked Questions

Short answers to common questions about how the licensing system works, updates, reseller accounts, and support.

1. Do we have access to latest updates of softwares?

Yes, the licensing system only connects the license checker to its own servers. Updates still come in realtime from the official software provider.

2. Can I move my license to another server?

Yes, you can change the license IP multiple times from the client area for your license.

3. Installing or uninstalling the license will harm our data?

No, the licensing system does not edit your data files and does not cause data loss.

4. Will you have access to our server files?

No, the system is designed to respect privacy and does not provide file-level access to customer servers.

5. What are the benefits of a reseller account?

Resellers usually get API access, WHMCS modules, a reseller panel, whitelabel options, and discounted license pricing.

6. Will license prices change in the future?

Pricing is intended to be stable long term, but may change if upstream vendors adjust their own prices.

7. Do you provide API docs and demo?

Yes, API documentation and demo panels are typically available so resellers can integrate and test before going live.

8. How can I follow updates and contact support?

You can follow announcements on official channels and contact support via tickets, social media, or chat for discounts, bulk deals, and technical help.

Security

Security Tips for cPanel

Basic hardening tips for login URLs, firewall setup with CSF, and securing SSH access on cPanel servers.

Login to cPanel and WHM safely

Always use a hostname or domain with a valid SSL certificate instead of raw IP addresses when logging into cPanel or WHM.

With SSL (recommended)

cPanel: https://example.com:2083

WHM: https://example.com:2087

Without SSL (not recommended)

cPanel: http://example.com:2082

WHM: http://example.com:2086

Port	SSL	Non-SSL
2083	Yes	No
2082	No	Yes
2087	Yes	No
2086	No	Yes

You can also use the auto-login URLs:

cPanel: https://example.com/cpanel
WHM: https://example.com/whm

Firewall: CSF

CSF (ConfigServer Security & Firewall) is a popular firewall for cPanel servers.

Install CSF:

cd /usr/src
rm -fv csf.tgz
wget https://download.configserver.com/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

Test required modules:

perl /usr/local/csf/bin/csftest.pl

If the script does not report any FATAL errors, CSF should work correctly on your server.

Full documentation: https://www.configserver.com/cp/csf.html

Secure SSH

Avoid using the default SSH port 22. Choose a custom port, update /etc/ssh/sshd_config, open the port in your firewall, and then restart SSH.

Example: set Port 1527 and then run:

service sshd restart

Remember to keep at least one open SSH session while testing new firewall and port settings.

LiteSpeed

Verify LiteSpeed license core number

Check how many LiteSpeed worker processes are running to confirm your licensed core count.

1. Determine core number

Run the following command to list LiteSpeed master and worker processes:

ps aux | grep litespeed

Count the number of LiteSpeed worker processes (lshttpd with #01, #02, etc.). That count is your LiteSpeed licensed core number.

Example output:

root      5344  0.0  1.0 21474956380 41452 ?   S    16:00   0:00 litespeed (lshttpd - main)
nobody    5347  0.2  4.3 21474999300 167916 ?  Sl   16:00   0:02 litespeed (lshttpd - #01)
nobody    5348  0.2  4.3 21475018528 167764 ?  Sl   16:00   0:02 litespeed (lshttpd - #02)
nobody    5354  0.2  4.3 21475017464 169564 ?  Sl   16:00   0:02 litespeed (lshttpd - #03)
nobody    5361  0.2  4.1 21474999752 161328 ?  Sl   16:00   0:02 litespeed (lshttpd - #04)
nobody    5366  0.2  4.3 21475015736 168296 ?  Sl   16:00   0:02 litespeed (lshttpd - #05)
nobody    5372  0.2  4.3 21475015324 169664 ?  Sl   16:00   0:02 litespeed (lshttpd - #06)
nobody    5378  0.2  4.8 21475021156 188424 ?  Sl   16:00   0:02 litespeed (lshttpd - #07)
nobody    5384  0.2  4.0 21475000400 158732 ?  Sl   16:00   0:02 litespeed (lshttpd - #08)

In this example, there are 8 worker processes (#01 – #08), which means an 8‑core LiteSpeed license is installed. If the count does not match your order, contact License.com.pk support.
