How do I fix this?

This randomly happened and I don’t know how to fix this?

Parse error: syntax error, unexpected ‘(‘, expecting T_STRING in /homepages/12/d258050551/htdocs/breezejmu.org/wp-includes/deprecated.php on line 1793

I looked into the code but don’t understand it. This is what’s on line 1793 in the php file.

function ( $text, $domain = ‘default’ ) {
_deprecated_function( __FUNCTION__, ‘2.9’, ‘_x()’ );
return before_last_bar( translate( $text, $domain ) );
}
