Fresh install of CiviCRM on a WordPress multisite yet no interface loads on the status page - seems that all the assets throw a 404 error causing this.
Tried updating from 5.18.1 to 5.18.2 but no success.
I'm with Demerit - it looks like there's a mismatch between your Resource URL and your base directory. Check your
civicrm.settings.php. Ensure that it is a) correct, b) doesn't contain a symlink. If it contains a symlink, rewrite the path to be whatever the symlink(s) resolve to.
So after looking at this closer and working with a colleague, we found that disabling cache for the assets worked – Status page angular load error
