Php debugging - can't see little bug


I am trying to debug a php application. I have checked the '‘show debugger at break’, I have set a breakpoint, but when I run the application nothing happens. I read through the topics and I am supposed to see a ‘small debug’ bug on the top of the screen and toggle it on and off ,but I don’t see it at all. What I am doing wrong ?



I found the little bug… was looking in the wrong place, but now I get 'debug connection error #1… any thoughts ???
