Cannot read property 'name' of undefined


When I try to access image in panel it trows error “Cannot read property ‘name’ of undefined”, after clicking on error “Cannot read property ‘tabs’ of undefined”.

Do you have any idea what can cause this issue?

when try to delete:

I use Ngnix + Cloudflare


All files have 404 error. Looks like something with permissions, but I cant find exact issue.

Update: After removing Cloudflare all works!
