Changes to prestashop theme not reflecting [closed]

Question

I have a Prestashop installation in which I have duplicated the original theme and I'm making changes to it. I have chosen the duplicate theme from the admin panel. The problem is that the theme is not reflecting any changes that I am making to the theme's smarty files. I have checked using firebug. I replaced the contents of global.css and it took away the styling from the site, but when I made changes to header.tpl, footer.tpl, etc. it does not reflect. Again I checked using Firebug: CSS is mine but HTML is not.

I am running PrestaShop v.1.4.6.2

Please help with this. I haven't the slightest idea as to what is wrong.

Thanks in advance.
