Add to Cart & Checkout Buttons Direct to Blank Page. Help Please!

I'm a ZenCart Newb - still tweaking my website: Kids Team Spirit
I've learned all I know about CSS and PHP thanks to this forum, Wiki and the book. Thanks to all who contribute! :thumbsup:

Problem
When I add an item to my cart, it directs me to a blank page. If I hit the back button, it shows there's an item in the shopping cart. I'm able to "view cart" but the same occurs if I click "go to checkout".

I know this is a coding issue since I switched back to the Classic template and it works fine.
:oops:

Your help will be GREATLY appreciated :)
Thanks in advance! :cheers:
Meh!

I just found this FAQ article on blank pages by searching for "blank page" in the FAQ area: https://www.zen-cart.com/tutorials/index.php?article=82

Using the utility mentioned in it will probably show you that you have a "Headers cannot be sent" error, which can be dealt with by another FAQ article: https://www.zen-cart.com/tutorials/index.php?article=87 ... once you have the actual error details in hand.

Thank you SO much, DrByte! That did the trick! You're awesome!
