Sidebar missing with Javascript errors (only for some users)

Hey Guys,

Working on a project with a friend, and he can see everything working fine in the modx manager. However I can’t see the sidebar with the resources / elements etc...

I have seen this before and it seemed to randomly fix itself. Tried all the usual account permissions / clearing caches / different browsers and just can’t seem to fix it.

I’ve attached a screenshot of the errors.

We haven’t modified any of the javascript, its strange its happening only for me. (both using the admin account to login).

Hope someone can help!

Cheers
Joe
