I am trying to extend the Luma Theme in Magento 2,

But it does not work as expected.

I added my Theme,

let it extend from Luma,

flushed all Caches,

Published all Statics and activated the Theme in the Backend.

I would expect, that the Frontend looks like the standard Luma Theme which comes with Magento2,

but it lookes like the standard Blank Theme. No Images, no luma Content, nothing.

Is there anyone who can help? This is my theme.xml

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
<title>My Theme</title>

    UPDATE I opened pretty the same question at the magneto2 github. They replyed me and told me that it is not recommended to extend the luma theme anyway, because its only a demo theme even you like to have the look and feel of the luma theme.github.com/magento/magento2/issues/2547 Commented Dec 1, 2015 at 8:19

along with theme.xml, you need to have below files in your custom theme, you can copy from luma and put into your custom theme and change it /app/design/frontend/Custom/default/theme.xml

  • along this copy etc, web, i18n and media folder from luma and paste into you custom theme
  • then clear cache and pub static folder
  • go to DB browse table called theme in that last entry will be your custom theme make sure parent id should be id of luma else delete that row and again open website

Note:- make sure in admin select your custom design and also run bin\magento setup:static-content:deploy to re-create pub static folder
