"Nothinge Selected"

Help me. I am a beginner
After importing Standard Assets for Unity 4.6,
“Nothinge Selected” is displayed in all prefab scripts.

How can I fix it? It’s very troubled!
I am not erasing scripts or renaming them.

Currently I am using unity version 2017.3.0 f3.
The OS is win10

hii

you should see in console dialog there is something wrong in scripts and after that read the red alarte to see where is the problem
