Codeigniter not running class definitions - PHP or Apache config problem

I just uploaded working site files to a new server which I know is likely to have php/apache config problems as I've had to work with the server admin to sort them out to get this far.

When I visit the the site I don't get any errors just a blank pag开发者_开发知识库e. I know that the default controller is being run as if I echo something outside the class it gets printed but the same inside the class constructor does nothing.

I expect this to be related to a server config issue as I have had the site working locally and live on another server for over a year but it is possible that there is something wrong with the codeigniter setup.

Any help greatly appreciated. Cheers

Turned out that the new server had a slightly upgraded version of PHP which required me to update Codeigniter. After the update it worked fine.

Strange that it didn't produce any errors though
