This is noted elsewhere but not explicitly so i had to dig a bit. I had a CI application working and running on two machines. However when i ported it to the live server it gave me a blank page with no warnings or errors.
In my case the cause turned out to be that i had not installed MySQL bindings in the Apache server. However when trying to track it through it appeared to fail on the first controller it got to when calling Controller.php.
Confusingly a clean install of CI worked fine but of course tha didn't try to make the database connection.
After getting it running the captcha picture would not show up but as we were suspicious of the install this was easy to spot and was the missing GD library.
Just to not with trawling the posts here blank page problems seem to be often caused by MySQL access problems, misconfigured call to them and the autoloader.
Thanks for the other poster and responders who helped me work it out.
