Uninstall WHMCS

If you need to uninstall WHMCS from your server, you can manually remove the files, data, and cron jobs that comprise the installation. Specifically, you will need to:

  1. Delete WHMCS’s files and folders.
  2. Delete the database.
  3. Delete WHMCS’s cron jobs.
  4. Disable email piping and importing.
Before you remove WHMCS, make a full backup of the configuration.php file and database. If you want to resume using WHMCS in the future or need to access your data, you will need this backup.

1. Delete WHMCS’s files and folders.

Typically, you should delete every file and folder within the main WHMCS directory. However, if other data that you want to retain exists in that file structure, you should delete at least the following files and folders:

Files

Delete the following files:

aff.php              affiliates.php        announcements.php
announcementsrss.php banned.php            cart.php

Folders

Delete the following folders:

crons       downloads   feeds
includes    lang        modules
oauth       pipe        resources
status      templates   templates_c

2. Delete the database.

You can delete databases using many different methods. For example, you could use phpMyAdmin, the MySQL® command line interface, or through your control panel.

For help to do this on cPanel & WHM or Plesk servers, see:

3. Delete WHMCS’s cron jobs.

Find and delete all of the cron jobs that you have configured to run for your WHMCS installation.

Typically, WHMCS installations use the following cron jobs:

  • cron.php
  • domainsync.php
  • pop.php
For more information, see System Cron.

4. Disable email piping and importing.

If you previously configured email piping or email importing, disable them.

  • For email piping, delete any forwarders that currently pipe mail to pipe.php.
  • For email importing, delete the /crons/pop.php file.
