Selecting Category from Location page shows "Not Found"

Hello,

When I select a region from Location Switcher in the main menu, for example Arizona – “Popular categories” appears in the featured area. But when I click on any of those categories, I get “Page not found”.

However, this doesn’t happen if I select both Region and City. In that case it works fine. It doesn’t work only when just the region is selected..

I’ve cleared the cache, reset permalinks, deactivated GD Bosster, there are no other plugins installed except for GD ones, tried different browser.. almost everything that came to my mind..

Can you please look into this as soon as possible? I don’t normally ask for support on things I can handle myself, but this is just weird 🙂

Thanks
