Left mouse button is not working

I have a problem where my left mouse button do nothing. Other keys work just fine. I have some problems figuring out exactly where did I mess up. :smiley:

I’m building upon the First Person Template and have “Enable Click Events” on and in my Player Controller.

Edit: Yup, it’s gone again… What is causing this?

I got some keys setup within my player blueprint to print string. All work except left mouse button. I got all 3 keys binded in the Project Settings.
