Thank you for the help. I already did it and it worked a bit. But there were other sections of the theme which were broken. Finally, after spending some more issue, I found that after upgrade to Magento 2.1.16 somehow the theme fallback is not working. I am using
custom theme -> child of Smartwave Porto theme -> child of Magento Blank.
static_content deploy, the CSS from porto is not loaded especially for Checkout module. I copied the files from porto to the custom theme and it worked. BUT:
- I DON'T THINK IT IS PROPER SOLUTION
- AND ONE MORE THING THE WHOLE THING IS WORKING FINE ON LOCALHOST WITH APACHE 2
- It BREAKS ON MY STAGING SERVER - NGINX SERVER
