Visual editor and admin bar broken – jquery errors

Hi,

I was updated my site yesterday (to 4.2.1) and the admin bar is broken. It doesn’t appear up top but instead is all splayed on the bottom of the site. I tried to edit a page/post today and the visual editor is broken, leaving only a text editor. I also can’t edit the title of the post/page or the pretty urls. I am using multisite and this happens on both the root and 2nd site.

I have:
– made sure the box is unchecked in the admin profile page for text editor only
– disabled all plugins to check if there was something wrong
– changed themes to the twentyfifteen to make sure it wasn’t my theme
– tried to add define( ‘CONCATENATE_SCRIPTS’, false ); to wp-config
– updated to 4.2.2
– reinstalled the update
– turned on the debug mode and here are the jquery errors from edit post

I googled some of the errors but I’m not sure how to proceed. Appreciate any help, thanks!
