set_status_header results in blank page

[eluser]gRoberts[/eluser]
Hey all,

I've asked about this in the past but unfortunately it produced no results.

Hopefully, a new thread will reach a new audience.

Basically, I have a Linux reseller account provided by http://www.fasthosts.co.uk and I have noticed a strange issue when issuing 404 errors.

When ever CI fails with a 404, it produces a white page. That even includes instances where you call show_404();

I've found that by removing set_status_header in the Exceptions class (line 118) it works but this results in a header result of 200. This obviously is wrong.

Has anyone ever encountered this and found a solution?

Thanks

Gavin
