Product name not showing in checkout

Hi,
When in the checkout of my website the customer can only see sub total and postage info not the name of the product they are buying, this happens in the payment info page and confirmation page.
Also my site does not give all the information to paypal, address is not shown and neither is product title on the order
Any ideas
Many thanks
David

We won't be able to help without a link to the site.

Ok, we 1st need a link to your site to help further.

You could try this. If you have the 1.5.1 download on your PC, re-upload the following files found in: includes/templates/template_default/templates/tpl_checkout_confirmation_default.php
includes/templates/template_default/templates/tpl_checkout_default.php
includes/templates/template_default/templates/tpl_checkout_payment_address_default.php
includes/templates/template_default/templates/tpl_checkout_payment_default.php
includes/templates/template_default/templates/tpl_checkout_shipping_address_default.php
includes/templates/template_default/templates/tpl_checkout_shipping_default.php
includes/templates/template_default/templates/tpl_checkout_stacked.php
includes/templates/template_default/templates/tpl_checkout_success_default.php

Just re-upload them from the core file to your site via an FTP program (core FTP Le) for example.

So provide a link to your site and we will see what
