Cart page not using latest modified template

I update my primary template that is used throughout my website. I went into my cart settings and made sure that this template was specified. However, my cart still uses the old template. I tried clearing my browser cache, but this did not help.

Any solutions. My website is
www.sweetlightgallery.com

To see the problem add an image to the cart, and then go to the cart page.

A second question. Is there a way, when the cart has an item added to it, to have the cart icon appear while still looking at a full size image in an album. When person adds an image to the cart, they are returned to the full size image view. They have to exit the slide show mode, then they see the cart icon, that can be clicked on to take them to the cart page where they can check out. It would be nice if they could access the cart check out page while they are still in the slide show mode.

It looks to me like your main page and your cart page are using the same page template (id 54)
In Backlight, try going to the Cart main dashboard and clicking on Reset the customer’s cart in this browser
Also try clearing template cache.

Matt or Ben will have to address your second question

Thanks Rod, that corrected the problem. Look forward to seeing if Matt or Ben have an answer to my second question.

There is not a way to get to View Cart page without exiting the slideshow.
