I had a slider on my home page. I changed it, (or so thought I changed it), from a slider to a static image. This somehow killed my mobile responsive design. On some browsers I see the old slider, on some-the new photo, on others-no photo. It seems that the layout is also whacked on phones, however now the phone icon is missing from my upfront builder so I am limited in how I can affect responsive design. Thoughts or suggestions?
