"Change Post" screen is half-empty

We built a blog using djangocms-blog and tested it extensively on our local environment. We’ve just deployed it to a staging environment and the “Edit Post” screen is somehow empty:

There are no failed requests or Javascript errors. We loaded the exact same data via a fixture, so the data should be exact same as well.

As a comparison point, this is what it looks like on our local dev:

Any idea why this is happening? We have absolutely no clue where to look.

Thanks

yes, “add post” looks similar:

I’ll try the pip freeze command shortly

@bbirand can you test aldryn-apphooks-config 0.4.0rc1? That should fix this problem
