Notices on or off, they will be back in the forums for help anyway.
Is asking for help a bad thing then?
Asking for help is a good thing, especially if the person learns from it. But don't shoot yourself in both knees by trying to save some time by being lazy.
Suggesting that a problem doesn't exist anymore simply because error notices are turned off is not a good thing.
Just like the train that still will hit you, even though you closed your eyes and don't see it coming.
Code should not produce errors/warnings/notices when "operating normally". Usually it's a simple error like in this case and easy to fix.
If you don't fix it, you'll miss the more serious errors simply because of the size of the error log.
If you turn error messages off, you'll miss every chance to fix an error before it blows up right into your face.
