hi @M_Guen it looks that height of your browser is too small. Why do you have it set this way? When you increase height to normal size you should be fine. There is no warning on window height as it is on window width when you shrink it under required width to be able work in WF.
Hey @Stan, thank you very much :)) I am really new in those webdesign-issues - as you could see
I increased the height to normal size and its working… thanks a lot!
