This interface allows you to add, manage, upgrade, and remove cPanel Addons (cPAddons). cPAddon software packages add useful functions to your website. For example, cPAddons can run blogs, bulletin boards, ecommerce software, guest books, and other services.

  • We have deprecated this interface. For more information, read our cPanel Deprecation Plan documentation.
  • This feature only appears if your hosting providers enables it.
  • WebPros International, LLC does not develop or maintain the cPAddon software packages (for example, WordPress®). We only include these packages in cPanel & WHM to facilitate distribution and installation. For assistance with a cPAddon, contact your hosting provider or the software developer.

Update Notifications

You can enable or disable cPAddon software update notifications at the top of the interface. If you enable notifications, the system will email your cPanel account’s contact email address. You can set your account’s contact email address in cPanel’s Contact Information interface (cPanel » Home » Preferences » Contact Information).


Hosting providers can also add the .cpaddons_notify file to the /home/username directory to enable software update notifications. In this directory path, username represents the cPanel user.

Configure cPAddon

To configure a cPAddon, click the name of the cPAddon that you wish to modify. A new interface will appear.


Your hosting provider selects which cPAddons to make available to you. If you require additional cPAddons for your website, contact your hosting provider.
