Magento Copy To New Server - No Errors Logged, displays white page

I am trying to move a magento installation (v1.5.0.1) to a new server and new url. I have followed the instructions here (with the exception that I want to keep my current version of magento and extensions)-

http://www.magentocommerce.com/wiki/groups/227/moving_magento_to_another_server

The admin login works, but nothing is displayed below the header after I login. The ajax search box on admin shows my products when I start typing, but the product page is never displayed.

The store home page shows a blank page.

I have checked both a开发者_StackOverflow社区pache and magento logs and neither shows any exceptions.

I have tried to copy this to my dev Windows machine and another linux server. Both have the same result. The database seems to be working fine, but something in the rendering of the page is breaking and getting eaten up by Magento.

Any suggestions?

Did you check the php error logs? Did you try turning on display_errors in your php.ini file?
