iOS/Phonegap: jQuery Mobile Error loading page

iOS/Phonegap: jQuery Mobile Error loading page

I have been using jQuery Mobile for a few years now for building apps based on Phonegap Build. Since iOS 10 it seems regular linking to sub pages results in "error loading page". What I do is very simpel:

index.html => a jQuery call loads the jQuery Mobile listview with:

<a href="item.html?id=1">

Next I have that file (item.html) which is linked to in the same directory, so the file does exist.

What could this be and why did it stop working? On Android is works fine btw. I have "cordova-plugin-whitelist" included in my project with the following option:

<allow-navigation href="*" />

Anyone that has had this problem and was able to solve it?
