404 errors and blank TinyMCE

  • After I updated WordPress and my plugins, the visual editor went blank. Firebug shows a bunch of 404 errors. These files actually all seem to exist but WordPress throws a 404 error anyway. I can access most ressources directly in my browser, for instance https://www.mysite.com/wp-content/themes/mytheme/logo.png, but not the ones creating the issue: they return a 404 although they exist in the queried location.

    I tried turning off javascript concatenation as advised here but that didn’t work.

    I tried deactivating all plugins, as well as reinstalling WP 4.6.1 to no avail.
    I have a dev copy of the site where everything is fine.

    Any ideas?
    Thanks,

    C.
