I couldn’t find anything about which permissions should be set in Shopware 6. In my local ubuntu system I can’t able to update any theme configuration fields.
Getting this type of error while click on save button from theme manager :
code: "0" status: "500" title: "Internal Server Error" detail: "Warning: chmod(): Operation not permitted" /var/www/html/shopware/development-126.96.36.199/vendor/league/flysystem/src/Adapter/Local.php
Thanks in advance
