4Command technical requirements

Platform

4Command runs on Joomla 3, 4 & 5 as follows:

  • Joomla 3: version 3.9.0 or more recent
  • Joomla 4: latest published version only.
  • Joomla 5: latest published version only.

4Command is only tested with Joomla native multilingual system. If using a 3rd-party multilingual system, 4Command should generally operate correctly but some or most features may not work as well.

Joomla 3.x support policy

Although this extension generally works fine on Joomla 3, we only officially support the entire feature set on Joomla 4 and up.

What this means is that there can be some new features added or modified that can only work on Joomla 4+. And some features may stop working on Joomla 3 in the future.

Administrator template

4Command is only tested and will only operate entirely as expected when used with Joomla default administrator template, using their default settings.

We expect it will also work fine with alternate configurations, but glitches may occur, for instance visual issues with colors or positions of buttons and dialogs.

PHP

PHP version 7.1.0 or more recent

MYSQL

MYSQL version 5.7 or more recent

Browser

4Command uses modern javascript technologies for its user interface. It requires a modern, "evergreen" browser such as Chrome, Edge, Brave, Firefox, Safari and similar, fully updated. Internet Explorer is not supported.

Operating system

4Command is tested on Windows and MacOs. It should likely work as well under various Linux distributions, but:

  • we can't garantee that
  • we likely won't fix any issue related to using 4Command under Linux, for we'll lack the required devices and experience

Keyboard shortcuts compatibility

Keyboard shortcuts usage

4Command makes extensive use of keyboard shortcuts. Some browsers, or extensions running in your browser, do prevent the use of some keyboard shortcuts, as they keep them for their own usage.

Likewise, your operating system may also prevent 4Command to use some keyboard shortcuts for the same reason.

We do test extensively but this is a moving target and sometimes you just won't be able to use one or a few 4Command shortcuts on your machine. Using another browser or another computer may resolve the issue.
