Overview

This document describes how to enable the cPanel Meridian theme for your customers. Meridian is cPanel’s goal-based theme. Instead of organizing tools by category like Jupiter does, Meridian groups features into six purpose-built hubs based on your cPanel user goals.

Set Meridian as the default theme for new cPanel accounts

To set Meridian as the default theme for new cPanel accounts, perform the following steps:

Log in to WHM.
Navigate to WHM’s Edit a Package interface (WHM » Home » Packages » Edit a Package).
Select the default package and click Edit.
In the cPanel Theme menu, select Meridian.
Click Save Changes.

Understand when cPanel account users can switch back to the Jupiter theme

Whether a cPanel account user can switch back to the Jupiter theme depends on whether you created their account on Meridian or on Jupiter. This behavior is fixed and you cannot configure it:

Accounts that you created on Meridian cannot switch back to Jupiter themselves, regardless of the Theme Switching feature setting.
Accounts that you created on Jupiter, or that you moved to Jupiter at any point, can switch between Meridian and Jupiter as long as the Theme Switching feature is enabled.

Note:

This restriction only applies to the cPanel account user’s own theme switching. You can still change the theme yourself for an account that you created on Meridian. For example, use WHM’s Modify an Account interface (WHM » Home » Account Functions » Modify an Account), change the account’s package, or use cPanel’s UAPI Themes::update function. After you move the account to Jupiter, the account switches themes normally.
