 * Hi,
    when i use query monitor my front-page.php get broken. [http://prntscr.com/nix70v](http://prntscr.com/nix70v)
   Its visible ony for logged in users visitors can see the normal page. Why this
   happen? I tried to go line by line in my wordpress code and cant find any error
   in queries etc. I use my started theme which is pretty much bones of wordpress.
   What can cause this internal server error? (i tried disabling all other plugins).
   Backend query monitor works normaly and i can check queries.

 * Can you check your PHP error log to find the fatal error message?
