Answer 1

I have resolved it in three steps:

1. Replace the minicart.phtml file from theme (app\design\frontend\Theme_namespace\Theme_module\Magento_Ch‌​eckout\templates\car‌​t) with core template (vendor\magento\module-checkout\view\frontend\templates\cart‌​).

2. Replace content.html file from your theme (app\design\frontend\Theme_namespace\Theme_module\Magento_Checkout\web\template\minicart\content.html) with core template (vendor\magento\module-checkout\view\frontend\web\template\minicart\content.html)

3. Remove all pub/static/frontend , remove var folder. Run deploy static content again : php magento setup:static-content:deploy

Result minicart after fixed :
