you need install this PCF8574 arduino library.
here is download file for you.

I have put the PCF8574 library, under library folder, under sketchbook location. 
For my case it is C:\me\codes\arduino\libraries
And it worked. 
   

But, now the below compile error came back.

Code:

Compilation error: WiFiManager.h: No such file or directory
