  • You need to set your theme from admin then your code will work for you. Jun 20, 2017 at 10:59

First you need to check theme is applied or not. You can check your current theme by ctr + U, you can see current theme path in .css and .js file.

In your case Magestore/Sample display in .css and .js file path. If display it, theme is set properly.

Run below command

php bin/magento setup:upgrade

php bin/magento setup:static-content:deploy

php bin/magento cache:clean

Now you can see your changes.

Let me know if you have any query.

You have to simply override login.phtml file in your theme app/design/frontend/Magestore/Sample/Magento_Customer/templates/form/login.phtml no need to write in layout file

 echo $welcomeMessage = "Login Page";
