Problem with Notices

I have the following error writes set in my php.ini file: error_reporting = E_ALL & ~E_NOTICE For a long time, that worked just fine - giving us only errors/warnings that we needed to see. Now, all of a sudden, we are getting notices written to the error file. It's a problem because there are a number of valid ones, and they get in the way of trying to track down genuine errors. I've tried creating a new php.ini file; I've even copied a new php directory over from a working machine. No luck. Any clue as to how we can ditch these notices? thanks Madeleine D.
