Interface Lock Scripts


Overview

In cPanel & WHM version 11.52, we added scripts to manage the Interface Lock System. We created the Interface Lock System to block user changes to various features during cPanel & WHM upgrades. The Interface Lock System can manage global or user-specific blocks. This document contains the scripts that you can use to mange the Interface Lock System.

Warning:
  • You should only use the scripts provided in this article for maintenance purposes.
  • Do not use these scripts unless cPanel support instructs you to do so.
