How to show a error page when there is a php mistake?

[quote author="Jelmer" date="1280266004"]It's not in there because not all configurations of PHP allow it. Just add it.

And turning UhOh off can be a problem. I added a config option myself with my IP and only show the extensive errors when I'm the one requesting it and modified the class to show a general error when the request was made by someone else.
I can't just post the code because I did it in my own CI fork (AugmentedCI in my sig) and merged the CI_Exception class with UhOh. But you can see what I did on BitBucket on lines 76 and 370.[/quote]

uhoh I think this is a little advanced for my knowledge. Thanks anyway
