Moved Server, Same Domain – Can’t Log Into WP

Hi WordPressers

I’ve just moved to a VPS server (was previously on a shared host). Transferred everything across, everything looks okay but I, nor any of my contributors, can log into WordPress – we get blank screens. The meta block has re-directs, and the WP-Admin path, ie

http://wordsmoker.com/wp-admin/

comes up blank too. Nothing is generated (in the page source.)

Anyone got any ideas? I, of course, have checked the forums, and seen other requests address this issue. I’ve checked them all against my files and db structures, etc, to no avail.

Many thanks in advance for any help you can provide.
