I am trying to run php through localhost in Opera.
I am always getting string + int error.
I am not getting this error neither when I run in Firefox nor the online website.
Is there any way to turn this feature off in Opera Settings somewhere.
(where I can choose if I want this error to show up or not)

Is it possible to change the Opera Developer icons in the software from red to the whiteish/grayish icon of Opera Developer system tray icon, to avoid confusion between Opera and Opera Developer?
