There are absolutely no errors shown in the Console on Chrome. All I see is a “JQMIGRATE: Migrate is installed, version 1.4.1” message with the file path in the admin folder.
I found this out tonight. Apparently jetpack has a new feature to add a mobile theme. (Obviously for themes that aren’t responsive or have a mobile site.) This is turned on by default. Just go into the Jetpack settings and turn it off. Problem solved.
