Hi, the included file jquery.nivo.slider.pack.js does not work really well with jquery-3.1.1, throwing errors and stops working if you try to activate Navigation
Show navigation prev next in the modules admin. To get it working change inside jquery.nivo.slider.pack.js  $(window).load(function to  $(window).on("load",function and search for .live (you'll find 2 instances), change them to .on et voila works without errors next previous working too. Best regards Christoph
