How to prevent CI from reporting PHP Notice errors

Yes, it's 3.x, I've followed the documentation, and you can clearly see that on the 'development' environment I've changed the log level via error_reporting() to display all errors except notices, strict errors and user notices, but for one reason or another CI is still outputting those errors.

In the file application/config.php I have also set $config['log_threshold'] = 1;

Why is CI still outputting notices? What am I missing?

Very strange!
I tested on my server and it works...
1. perhaps'a you may have an overlaod controller for Exceptions (search under application/core)
2. maybe you have a try-catch-finally block on your own controller
3. be sure the CI code is clean: you must have in line 612 (system/core/Common.php):

PHP Code:

if (($severity & error_reporting()) !== $severity)
        {
            return;
        } 


can you post the controller source code that has this problem
