Unity refuse to compile my scripts

Unity refuse to compile my scripts. It says I need to fix the errors but the console doesn’t show any error message. I have tried reimporting all but it doesn’t fix the problem.
What can I do?

In the console there are toggle buttons that control what messages display. Make sure “errors” is toggled on.

I know that and it is not the problem.
The problem is Unity does not compile the scripts and they are not loaded to the gameobjects. The scripts appear with the warning icon in the editor, (the public variables are not showed).
If I change any script to force compilation, when saved, the compiling is aborted (finished) abruptly, and no errors are showed.
