It looks like PHP 8 changed the signature for the Imagick::clear method. This error should be fixed in the next release (4.1.4), by using a different class for PHP 8 environments.

In the mean time, the easiest solution is to disable VaultWiki's Imagick support when in PHP 8 environments. This will be applied in the next build of 4.1.3. In src/addons/vw/vw/_core/model/image/format/vw.php, find:

Code:

if (class_exists('Imagick', false))

Replace with:

Code:

if ( class_exists('Imagick', false) AND ( version_compare(PHP_VERSION, '8.0.0', '<') OR vw_Hard_Core::model('Version')->installed('4.1.4') ) )
