I appear to be having the same issue reported by justjim. When selecting a city in the location switcher, the URL comes up as (sitename)/locationaustralia/new-south-wales/(cityname). I get Error 404 – Page not found!
If I manually insert a slash to make it …/location/australia/… then the correct city sometimes (but only sometimes) appears in the location switcher immediately. More often, however, the site becomes unresponsive and I get “This page can’t be displayed” (Internet Explorer 11, but the same behaviour in Google Chrome as well).
If I wait a bit and then refresh the browser, the correct city appears in the location switcher, but I still get Error 404 – Page not found!
If I then navigate to another page via the top menu, the location switcher sometimes (but only sometimes) retains the correct city in the location switcher, and the map of that city appears with the place listings for that city – in other words, the site works.
More often however, the location switcher reverts to Change Location (i.e. Everywhere) and the location switcher just stops working altogether.
Any help would be appreciated. If I can get this to work as intended, it would be ideal for my site.
