I have set up new 1.9.3 magento. I have a css files present in default/default folder. It does not present in custom_package/custom_theme and custom_package/default_theme. It is going directly to the base/default. It should check in default/default. is there any way to achieve the proper fallback.
You need to create a Fallback by set up etc/theme.xml
for each theme like below:
In custom_package/custom_theme/etc/theme.xml
file set as:
<?xml version="1.0"?>
<theme>
<parent>custom_package/default_theme</parent>
</theme>
In custom_package/default_theme/etc/theme.xml
file set as:
<?xml version="1.0"?>
<theme>
<parent>default/default</parent>
</theme>
In default/default/etc/theme.xml
file set as:
<?xml version="1.0"?>
<theme>
<parent>base/default</parent>
</theme>
