Ah, I see where you got it. You don't actually put the 'void' there or any of hte stuff that is light colored. So, it actually would look something like this:
PHP Code:
standard_error(something, something, something, something)
However, the last three 'somethings' are optional. And the first one is a string. So, you want something like this:
PHP Code:
standard_error('Groups is currently closed to improve its features.')
