Blank Jetpack 7.1.1 dashboard

Hi Guys,

When updating to Jetpack 7.1.1 from 7.0.1, I get the “blank Jetpack dashboard” issue similar to the one discussed here:

https://github.com/Automattic/jetpack/issues/11513

The Chrome Inspector console errors are nearly identical.

Waiting and refreshing the dashboard occasionally helps, but not consistently or permanently.

When this first happened, I tried the following:

1. Deactivated all plugins: No change
2. Deactivated/reactivated Jetpack: No change
3. Uninstalled/reinstalled Jetpack 7.1.1: Seems to solve the problem — But all settings are lost, so it’s a pain.

So far this issue has happened on 4 of 7 websites, all in Jetpack Dev Mode, and all on similar environments (see below).

My Environment:

* Chrome 72 on Mac Yosemite
* WordPress 5.1 with Classic Editor installed
* Self-hosted on WP Engine
* PHP 7.2
* Jetpack 7.1.1 in Dev Mode, typically with the following modules activated:
– Carousel
– Copy Post
– Sharing
– Sitemaps
– Widget Visibility

Thanks.
