I was sure I had done it the first time - but I went back and checked everything over, re-uploaded it all and the problem persists.
The only thing I found that needed merging was html_header from (yellow1912)cjloader.
I can see the test accounts I'm creating in the admin, so it's managing to insert into the users db but the page just doesn't load.
If I go back to the home page then try to checkout again, it just shows the blank page again. No source code at all.
