New server, think I've ingested data, but console errors

On first loading the page, and when trying to use any of the menus, I get this:
> Uncaught TypeError: Cannot read property '0' of undefined

coming from:
```javascript
var t = u.tileProxy.calculateZoomLevel(this._xScale, this.tilesetInfo.min_pos[0], this.tilesetInfo.max_pos[0])
```

Is this a bug in the software, or is it not installed correctly?
