How to Choose the Correct cPanel Interface Version in the Documentation

Updated

On docs.cpanel.net, choose the interface version that matches your server before following any interface instructions. The site offers two interface experiences, Jupiter and Meridian, and shows a version selector such as v138 for the cPanel and WHM interface documentation. Pick the version your account or server actually runs, then open the cPanel or WHM section; the instructions you see will then match the screens and labels you have.

What the selectors control

The documentation site separates its content along two lines:

Selector What it changes Where you see it
Interface experience (Jupiter / Meridian) Which interface design the screenshots and navigation steps describe The "Choose your cPanel experience" prompt
Version (for example, v138) Which release's interface documentation is shown Next to the cPanel Interface and WHM Interface entries

The site's own description of its sections confirms the split: "cPanel User" covers accessing your cPanel account, learning cPanel features, and navigating cPanel interfaces, while "WHM User" does the same for WHM. Both are presented with the version label attached, so the version is part of which page you land on, not a separate filter you apply afterward.

Step-by-step: picking the right version

  1. Find out what your account runs. Log in to cPanel or WHM and check the version number displayed there. This is the number you need to match.
  2. Open the matching section. On the documentation home page, go to cPanel Interface for end-user features or WHM Interface for server administration.
  3. Set the version. Use the version selector (shown as v138 in the current documentation) to pick the release that matches your server.
  4. Set the interface experience. If prompted with "Choose your cPanel experience," select Jupiter or Meridian to match the interface you actually see.
  5. Verify before following steps. Compare one screen in the documentation with the same screen in your account. If menu names or layout differ, you are on the wrong version or interface—switch and check again.

Why the version choice matters

Interface documentation describes specific menus, labels, and screen layouts. When the version or interface experience does not match your server, the instructions can point to controls that are named differently or placed elsewhere, and you may conclude a feature is missing when it is only described for another release. Matching both selectors first is the cheapest way to avoid that.

A concrete case: if you are troubleshooting a task in WHM and the guide references a menu path you cannot find, the usual cause is a version mismatch rather than a missing feature. Re-select your actual version and interface, then re-read the same page.

Other entry points on the site

The documentation home page also links to resources that are not version-specific in the same way, including:

  • Installation Guide — for setting up cPanel & WHM
  • EasyApache 4 and EA4 — for the web stack
  • Knowledge Base — for troubleshooting articles
  • Developer Documentation and API — for integration work
  • Manage2 and Webmail — product-specific sections
  • Release Notes, Change Logs, Roadmaps, and Video Tutorials — for version history and learning

Use these when your question is about installation, the stack, or the API rather than a specific interface screen. For interface tasks, always return to the version-matched cPanel or WHM pages.

Common sticking points

  • Skipping the experience prompt. If you dismiss "Choose your cPanel experience" without selecting, you may land on documentation for the other interface design.
  • Assuming the newest version applies. The version shown on the site (v138 in the current documentation) is not automatically your server's version; check your own account.
  • Using interface pages for non-interface questions. Installation, EA4, and API topics live in their own sections and are not governed by the interface selector.

The site notes that it logs search terms to improve its documentation, with details in its Privacy Policy—useful to know if you rely on site search to find a page, but it does not affect which version you should select.
