Steps to reproduce

Happens every time I access the page. Tried logging in/out and clearing the browser as well as cachets cache.

This does not occur on the demo site; https://demo.cachethq.io/dashboard/subscribers

I imagine something has gone wrong with one of the subscriptions. We're actively overhauling this system thanks for @joecohens, so it should be arriving within the next week or so.

[GrahamCampbell]

Try clearing the view cache.

Could you advise me how to do that?
