Magento 2.1.2 Child-theme front end no display

Question

I have duplicated the theme in app folder and modified the theme.xml accordingly. But it displays like below screen shot.

http://brick.learnup.ro/lux/

It should be look like this -

http://brick.learnup.ro/

I have to mention that I have successfully ran all the commands in SSH:

setup:upgrade setup:di:compile cache:flush setup:static-content:deploy

and set the permissions right.

The problem occurs only with the duplicates of this theme

Thank you

Answer 1

So the problem was I had forgotten to create the widgets for this new theme - with the "Design Package/Theme" set to it.

Answer 2

Copy the app & pub folder of your theme & paste it into your Magento root directory & from there fire the below command

To set & install the new modules of your theme.

php bin/magento setup:upgrade

To set & make visible the static content of your theme that is css,js,Images.

php bin/magento setup:static-content:deploy

For your convenience & making sure about it that every thing is ready run this command also to remove the cache

php bin/magento cache:flush

Basically the last command is used for the cache clearing.
