For cPanel & WHM 11.48

(Home >> cPanel >> Upgrade to Latest Version)


This feature allows you to update your cPanel & WHM software to the most recent build available on your server's Release Tier.

For example, if you selected the CURRENT tier in WHM's Update Preferences interface (Home >> Server Configuration >> Update Preferences), then this feature will upgrade your server to the latest CURRENT build.

Additional software updates

The script that this feature runs (/usr/local/cpanel/scripts/upcp) calls other scripts in the /usr/local/cpanel/scripts directory that will update most of the software on your system.

The following table lists the additional scripts and the software that they update:

Send Update Analysis to cPanel

This feature sends a log file from your update attempt to cPanel so that we can improve the quality of our software and the update process.

Forced Reinstall

This feature allows you to force a reinstall of the cPanel & WHM software, regardless of whether WHM detects that your system is up-to-date. This can be useful if any files are corrupt and you wish to reinstall them.

To update your cPanel & WHM software, perform the following steps:

  1. If you wish to send cPanel the log files from your update attempt, click the appropriate checkbox.
