There is a tab named "Console" (at least in German IE 11 it's "Konsole") where such (and other) error messages will be displayed. That's basically the same for other contemporary browsers, by the way. On you can learn more about the developer tools. In my opinion it's really worth to spend some time learning to use these tools; it'll pay back rather quickly. -- Christoph M. Becker
