testing server - fine, production - all blank!

I've attempted to trigger a blank page error myself with no success. Could you provide a copy of your controller or at least the declaration, constructor and index functions?

Since your code works on your dev server, there must be some setting(s) on your live server that are causing this error. There may be some quirk with PHP 4.4.7, but I'm not aware of any.
