Integrated stripe on staging server does not reflect in front end

Hi,
I have enabled stripe in test mode at admin settings with test secrete and publishable key. I have attached screen shot for same.

I get a js error in front end checkout saying
Uncaught TypeError: Unable to process binding “template: function (){return getTemplate() }”
Message: Unable to process binding “if: function (){return df.formTemplate }”
Message: Unable to process binding “template: function (){return df.formTemplate }”
Message: Unable to process binding “if: function (){return !hasCards }”
Message: Unable to process binding “template: function (){return df.card.newTemplate }”
Message: Cannot read property ‘name’ of undefined

I have no idea if any of previous developer has made code changes as I am new on this project.
