I have set this setting, but I don't know where to findt his logfile
EDIT: I just found out this is under "Debug Console":

Code snippet to reproduce:

Any code, since it won't start.

xDebug used to work properly, and since today when I try to access my website with xDebug active I get two requests in the callstack:
https://i.gyazo.com/1e44c6b118bd2f6232fe7f589f1fb8d4.png

And my website hangs (gets stuck).

Any idea what could be causing this?
