Hallo Community,
ich versuche gerade, eine Contao Installation auf den neuesten Stand zu bringen.
Obwohl die Seite bei Strato gehostet ist (ja... i know), hat es bisher immer funktioniert.

Wenn ich versuche, z.b. die codefog/contao-cookiebar Extension zu installieren, bricht die Installation über den CM immer mit der Meldung ab

Code:
$ /opt/RZphp72/bin/php-cli -q -d max_execution_time=300 /mnt/path/website2018/web/contao-manager.phar.php composer require codefog/contao-cookiebar --no-suggest --no-update --no-scripts --prefer-stable --sort-packages --no-ansi --no-interaction
