Debug::logfile of type true is incompatible with the type string expected by parameter $filename of fopen().

            if ($fp) {

$fp is of type false|resource, thus it always evaluated to false.

                $locked = false;

                if (function_exists("flock")) {
                    $tries = 0;

                    }

                        return;
                    }
                }

                fputs($fp, "[$ts] $message\n");

                if (function_exists("flock")) {
                    flock($fp, LOCK_UN);
                }

                                    return;
                }

            } else {
                user_error("Unable to open debugging log file: ".Debug::$logfile, E_USER_WARNING);

Are you sure Debug::logfile of type true can be used in concatenation?

            }

        print "[$ts] $message\n";
