Go to Checkout goes blank

hi
I just upgraded from V150 to V151 because I was having problem on the "go to checkout" screen. Every time my customer click on GO TO CHECKOUT its goes to a blank screen http://nikorybathtreats.com/index.php?main_page=checkout_shipping. After I upgraded, it still doing the same thing. Not sure where to look to fix it. the problem just started 2 weeks ago. Never done any update with my zencart for awhile.
I would appreciate any help on how to fix it.

Going by the dates I'm not so sure. Can you tell me the path to the folder in which you found these logs please?

Older versions dropped things in the cache folder, newer in the logs folder. Both are in the root.

That's what I was thinking too, wrong folder contents for this issue.

I have the same problem - upgraded yesterday 1.3.9 - 1.5.1. Going to checkout opens a blank page
