Hi
It seems you have not follow the steps.
The modules are empty.
Go to Site > Global Configuration and change the default WYSIWYG editor to 'editor – no editor'. If you don't change the default editor to no editor the WYSIWYG editor will change the JavaScript, even if you edit the HTML source.
Now add the code.
Also there is no issue found in template. Please check your google AdSense code and add it. It will work same for any template. If it's not working for protostar as well there is issue in your code and you have to check you adsense account.
