Problem Redirecting!

[monolift]

I am using ZenCart 1.2.6d. I recently cloned the flat rate shipping module which seems to have gone weill, but now I am having problems with the checkout process.

My shipping methods show up on Step 1 of the checkout, but when I click continue, I am led to a blank page. If I type in the URL for the checkout_payment page, my shipping selection has been successfully stored. I can then continue to step 3, but when I click continue on that page, I am led to another blank page. The order processes and I receive a confirmation email.

It appears that something is causing the zen_redirect function to fail, but I cannot tell what that is.

if you change shipping methods do you still have a problem?

Yes, I have removed all of my current shipping methods and installed only the free shipping and I get the exact same issue.

I have tested things a bit and I can see that it gets through the entire header on the shipping page, but it won't redirect.

The redirect will work up until the shipping function in the header include on the shipping page.
