I must have missed that one, thank you for the hint.
Support for PHP 7.3 was introduced pretty late in the development process for ILIAS 5.4. You will probably encounter some more bugs when using this PHP version. Usually they are fixed pretty fast once discovered. But if you're looking for the best tested PHP version, that would probably be PHP 7.0 (the same version test54.ilias.de uses).
