Applying Main Template to Checkout Confirm Page

Hi,

The problem comes from your template.
First, you need to check the CSS files in the header of both a normal page and that page:

So for the URL extonbeverage.com/shop-products/ you can see that your template adds a CSS file extonbeverage.com/shop-products/?css_request=1&diff=2073527235 to the header, and for the URL extonbeverage.com/shop-products/checkout/checkout/confirm.html it adds a CSS file extonbeverage.com/shop-products/checkout...est=1&diff=869499139 to the header.
So apparently, your template simply takes the current page URL and adds two parameters to it to generate that CSS file link. And then, on every page of your website, your template check if these two parameters are there and if yes, it sends back its CSS code.

However, the extonbeverage.com/shop-products/checkout/checkout/confirm.html URL will trigger the creation of the order and clear the cart. Once that's done, that URL is not valid anymore and thus will redirect the customer to the main products listing of the shop. And that's what you see if you open the CSS file extonbeverage.com/shop-products/checkout...est=1&diff=869499139 instead of getting your template CSS back, like you get when you open extonbeverage.com/shop-products/checkout...est=1&diff=869499139

The problem comes form the trick used by your template. Instead of using the current URL, it should use the homepage URL to construct its CSS file URL extonbeverage.com/index.php?css_request=1&diff=2073527235 regardless of the current URL.

So I would recommend you to forward that information to your template provider.
As a quick fix to circumvent that, you can :
- create a Joomla article with the thank you message you want
- create a link to that article in a hidden menu item via the Joomla menu manager
- edit your credit card payment method in System>Payment methods and enter the URL of that Joomla article in the "return URL" setting.
That way, instead of the default thank you page of HikaShop, it will redirect to that thank you joomla article page and thus that problem won't happen.
