I'm getting a JS error "Cannot call method 'reapplyIfNeeded' of null" when switching from one subsite to anouther using the selector in the admin area. Once switching, draging files to folders dosn't work. Refreshing the page each time makes it work, so thats a work around, but not acceptable for clients.
Has anybody seen this error before? Any fixes?
I'm also getting a lot of "Refused to set unsafe header "Connection"" errors whilst working in the admin area. Not sure if these are contributing to bugs or not
