In Joomla 4 the file '/templates/system/css/system.css' no longer exists. The index.php of the JA Simpli template contains the following lines:

if (version_compare(JVERSION, '4.0') >= 0) {
// SYSTEM CSS
$this->addStyleSheet(JURI::base(true) . '/templates/system/css/system.css');
}

This will load this file in Joomla 4 with a 404-error. The following lines prevent this file from loading:

if (version_compare(JVERSION, '4.0', 'lt')) {
// SYSTEM CSS
$this->addStyleSheet(JURI::base(true) . '/templates/system/css/system.css');
}

Is it possible to correct this change in a next version?

        In version 2.0.3 the problem with system.css still exists. The following error message appears:

        Warning: is_file(): open_basedir restriction in effect. File(/templates/system/css/system.css) is not within the allowed path(s): (/home/vhosts/.../:/tmp/) in /home/vhosts/.../httpdocs/templates/ja_simpli/index.php on line 69

        This is in conjunction with Joomla 4.3.3.

                carlbengston You can edit this file:

                root/templates/ja_fit/tpls/blocks/head.php

                and change:

                <?php
// SYSTEM CSS
$this->addStyleSheet(JUri::base(true) . '/templates/system/css/system.css');
?>

                To:

                <?php
if (version_compare(JVERSION, '4.0', 'lt')) {
// SYSTEM CSS
$this->addStyleSheet(JURI::base(true) . '/templates/system/css/system.css');
}
?>
