Important note on PHP 7.4 support
Users have reported problems with using PHP 7.4 with Kirby 3.
PHP 7.4 is not yet supported by Kirby, support will be added in an upcoming release. It is therefore strongly recommended to use PHP 7.2 or 7.3 in the meantime. If you have already upgraded to PHP 7.4, please contact @lukasbestle via direct message for further information on your next steps.
PHP 7.4 is now fully supported with Kirby 3.3.2.
