a PHP message appears using Simple template in combination with PHP 7.4:
Notice: Trying to access array offset on value of type int in <pathToWwwFolder>\htdocs\templates\jp-simple\warp\src\Warp\Config\Repository.php on line 243
This message also appears if you try to install languages after the installaton routine in combination with the quickstart package.
The result is that the installation of languages does not work.
I solved thr problem with checking that the array is != NULL but I am sure this is not the best way.
