It has to be something on your browser. There's no error reports being generated that I can see.

Have you tried a different browser?
Or your phone?

If you can recreate this please take a screenshot and send to UtopiaSupport@Utopia-Game.com so I can see, but then also try a different browser and your phone or a mobile device.

I've had reports come in from others that have had this issue and it's normally resolved due to extensions of some sort causing an issue, or the user trying to use shop items while under a sat account.
