Panel page is not accessible with the error: "Cannot use "parent" when current class scope has no parent"

Hm, support for PHP 7.4 was added with Kirby 3.3.2. I would assume that this causes the error, even though it’s a bit weird that it doesn’t happened locally. But same error was reported here: Local websites error - #11 by Fleix and was also due to premature update to PHP 7.4.

For Kirby PHP support matrix, see
