This is what worked for me, with 4.2.2:

2. For those who feel comfortable with editing files.

In class_core.php locate lines 5683-5685 (class_core.php is in the 'includes' folder)
Code:

case E_NOTICE:
// Just ignore these completely //
break;

Add lines for Deprecated and/or Strict errors as required ;

Code:

case E_NOTICE:
case E_STRICT:
case E_DEPRECATED:
// Just ignore these completely //
break;

This will bypass the additional error reporting.
