We are running
Zen Cart 1.3.8a

I have had a problem with getting a blank page when i checkout using a credit card. We have installed the beanstream module and paypal, when choosing paypal as an option, there are no blank pages....

when a customer choses to use a credit card, the page at the final check out goes blank. I have installed the debugging log, but frankly, the report looks greek to me..

Beanstream claims the error is in Zencart, I have been trying to fix this and i dont know what to look for, or what steps to take. Please can someone assist me in helping me fix this..??

here is the site link..
