Despite the following settings below, I often see the path to the file producing the error. How do I turn off ALL errors no matter what?
error_reporting = E_ALL display_errors = off log_errors = off
The display error statement is not what you actually want. You should change also the error_reporting value if you don't want to have the messages informing you about the error.
You should try this for all errors
this will keep letting you know about the errors but they will be invisible to other users..
