come in Europe, you don’t need F° 
The thing is that the code names the DHT library, but it doesn’t include the library.
When the code compiles it uses the library you have installed on your PC. If you have multiple versions of the library installed it will pick one of them, which may not be the one you expect.
Turn on verbose compiler messages in the IDE and look at the last few messages. It will tell you which library is used, and if come were ignored.

Thank you Pete, I will after thr race…

Think I have bigger problems then code, getting errors loading and I know the library folder is in the correct location and has worked before.
Putting this beg on hold until all is normal!
And I thank everyone for all the positive input in this matter.

Think you need to replace the space with an underscore for that library.
DHT Library > DHT_Library

That was it, Thanks.

EUREKA!
Download latest Blynk library here:
https://github.com/blynkkk/blynk-library/releases/latest
Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

*************************************************************
This example shows how value can be pushed from Arduino to
the Blynk App.
WARNING :
For this example you'll need Adafruit DHT sensor libraries:

App project setup:
Value Display widget attached to V5
Value Display widget attached to V6
