4SEF technical requirements

Platform

4SEF runs on Joomla 3, 4 and 5 as follows:

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

4SEF is only tested with Joomla native multilingual system. If using a 3rd-party multilingual system, 4SEF 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.

sh404SEF

For importing data from sh404SEF, only the most recent version of sh404SEF at the time of 4SEF release is supported.

PHP

PHP version 7.1.0 or more recent

MYSQL

MYSQL version 5.7 or more recent

Browser

4SEF uses modern javascript technologies for its user interface. It requires a modern, "evergreen" browser such as Chrome, Edge, Brave, Firefox and similar, fully updated.

It is not tested on Safari, although it should work there as well.

Internet Explorer is not supported.
