Can’t access subscribers list

Hi,

I have 60 subscribers to my blog, but I can’t access the list.
I go to Jetpack->Discussion->See subscribers list
But once I click there I get to an almost blank page with just a title that says “Elige un sitio para abrir Personas” (Choose a site to open People), and as a subtitle “o visita La Astrologa” (or visit La Astrologa, my webapge). Below that there’s a search box, but you can’t click on the search box nor type anyhting. And below that a blank box.

This has always been like this and I never bothered but now I would like to access the list.

I hope I can get some help with this. Thanks!
