Hi @neelav_barai,

Can you check your module structure?

    MyCompany
    `-- ExampleAdminNewPage
        |
        |-- Controller
        |   |-- Adminhtml
        |       |-- HelloWorld
        |           `-- Index.php
        |-- etc
        |   |-- adminhtml
        |   |   |-- menu.xml
        |   |   `-- routes.xml
        |   `-- module.xml
        |-- view
        |   |-- adminhtml
        |       |-- layout
        |       |    `-- exampleadminnewpage_helloworld_index.xml
        |       `-- templates
        |           `-- helloworld.phtml
        |-- composer.json
        `-- registration.php

Are the layout and template files in the right place?

Did you refreshed cache?

In which mode is your application?

Hi @Damian Culotta,

Yes the directory structure is correct, I have double checked it.

I have complied megento after completion, i have done any deletion of cache, can it do it like this : 

php -f bin/magento cache:flush

I am running in developer mode.

Below is my complete code:

 <p>Hello World!</p>

And after these steps i get the below screen:

[Rakesh Jesadiya]

You need to create xml file like below namespace,

C:\xampp\htdocs\app\code\BBC\ProdAdmin\view\adminhtml\layout\prodadmin_prodadmincontrol_index.xml

you have kept name Prodadmin_index.xml file. Please correct filename and clear cache and check,

[ravi2katre]

Please check route. Xml file. Route id= [xyzid] and layout file name must start with that id
