Admin orders page breaking when attempting to edit order if order isn't a download

Zencart 1.5.1
PHP Version 5.5.23
MySQL 5.5.36-log

We have just moved hosting, the site previously worked fine on the old host

The old hosts settings were
PHP Version 5.4.30
MySQL 5.5.42-cll

There are no debug logs being generated by this error

When i access the admin/orders page

The list of orders appears as it should

However when I click on the "edit" button to the right to view an order it takes ages to load then only loads as far as the customers name,

However if the order contains only downloadable products the page loads correctly

This is part of the source of the generated page right up to where it crashes

I have tried uploading a fresh page et from a new set of files but it doesn't seem to do anything

anyhelp would be appreciated

Aaaargh

Its the payment method not the downloads, when a customer has paid by Paypal I can't access their order, if they have used direct Credit I can view the order
