Was a 5, now a 3

Has anyone else had problems using wifi and the web server to sync recipes. I keep typing in the IP address but nothing. I really liked the app when I could do this (5) but for some reason I cant do that anymore(hence a 3). I cant figure out if its not compatible with upgraded Firefox, upgraded MAC OS, upgraded iOS or what. I have contacted the developer, but keep getting asked if I have done things that I have done. I hope/wish someone has a better suggestion, or guess I will be looking for another app.
