I have created a theme by using Luma (which extends from Magento/blank). This has been added in the backend and site is working fine. Any changes done to CSS (Less) are being reflected in the store front .
However, changes that I’m making in default.xml are not being shown. It’s as if the Magento is completely ignoring the file. The path I’m creating default.xml is in C:\xampp\htdocs\magento2\app\design\frontend\vendorMy\themeMy\Magento_Theme\layout
Can anyone please help? In certain forums there are topics saying that I may need to change the theme from virtual to physical but cannot find the table. Is this correct?
