I visited many sites for find solution of this issue.

But after creating system.xml and acl.xml Magento give me a report generated error.

Error

a:4:{i:0;s:140:"Notice: Undefined index: id in /usr/local/ampps/www/mgn2/vendor/magento/module-config/Model/Config/Structure/Element/Iterator.php on line 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->handler(8, 'Undefined index...', '/usr/local/ampp...', 59, Array)

Can you clarify this issues?

In your system.xml replace this

<tab>HelloWorldMVVM</tab>

with this

<tab>Pulsestorm</tab>
  • @Marius: Can you share a bit context? I get the same error but I'm puzzled what to enter in my case. – hakre Sep 23 '16 at 10:19

    you are referencing a tab that does not exist. Each <tab> tag has an id and this way you can add sections under certain tabs. But if you add a section under a tab that does not exist you get the error above. – Marius Sep 23 '16 at 10:27
