Led Matrix max7219 +DHT+RTC Problem

Good night, masters, i have a problem with led 40x8 led matrix where i use sketch from “Parola”, the problem is DHT and RTC sensor not running properly, just display the innate text from sketch parola , please help

This code I attach:

// Program to demonstrate the MD_Parola library
//
// Display the time in one zone and other information scrolling through in
// another zone.
// - Time is shown in a user defined fixed width font
// - Scrolling text uses the default font
// - Temperature display uses user defined characters
// - Optional use of DS1307 module for time and DHT11 sensor for temp and humidity
// - DS1307 library (MD_DS1307) found at https://github.com/MajicDesigns/DS1307
// - DHT11 library (DHT11_lib) found at http://arduino.cc/playground/Main/DHT11Lib
//
// NOTE: MD_MAX72xx library must be installed and configured for the LED
// matrix type being used. Refer documentation included in the MD_MAX72xx
// library or see this link:
// https://majicdesigns.github.io/MD_MAX72XX/page_hardware.html
//

// Use the DHT11 temp and humidity sensor
#define	USE_DHT11	0

Split your project into the basic tasks, i.e. reading the sensors and updating the display. Make every single task work, before combining them.
