Visitei muitos sites para encontrar a solução para esse problema.
Mas depois de criar system.xml
e acl.xml
Magento me dar um relatório gerado erro.
Erro
a: 4: {i: 0; s: 140: "Aviso: Índice indefinido: id em / usr / local / ampps / www / mgn2 / vendor / magento / module-config / Model / Config / Structure / Element / Iterator. php na linha 59 "; i: 1; s: 6391:" # 0 /usr/local/ampps/www/mgn2/vendor/magento/module-config/Model/Config/Structure/Element/Iterator.php(59) : Magento \ Framework \ App \ ErrorHandler-> manipulador (8, 'Índice indefinido ...', '/ usr / local / ampp ...', 59, Matriz)
Você pode esclarecer essas questões?
