Server-side / hosting requirements
JCE has the same server-side requirements as Joomla! and functions best with safe-mode off.
JCE 2.9.x requires PHP 7.4 or later, including PHP 8. Using JCE on servers running earlier PHP versions may work, but as earlier versions are now unsupported - https://www.php.net/eol.php - we suggest you consider upgrading your server to PHP 7.4 or later.
If your server is using the PHP Suhosin extension, the suhosin.post.max_vars option must be set to 1000 or greater.
An understanding of the Joomla! administrative functions is required, especially the installation and general use of Plugins and Components.
To use the popup features of the Image Manager Extended, Link and Media Manager, JCE MediaBox is recommended.
