V13 custom backoffice js not loading

I’ve just upgraded a website from v8 to v13. The backoffice has two custom sections with trees and lots of pages for admin functions. Locally everything works perfectly.

However when I publish it and run it on the server the files from app_plugins are not loading. The sections appear in the top navigation bar and the html templates load. It’s the angularjs controllers that are not getting registered. I’ve tried everything I can think of but am somewhat baffled.

  • The files are all present and permissions correct - I can load the js files in the browser.
  • I’ve tried running the site in debug rather than release.
  • I’ve tried converting the package.manifests into code and adding via builder.ManifestFilters().Append();
  • I’ve tried adding and changing RuntimeMinification settings
  • obviously caching turned off in browser(s) dev tools
  • deleted all temp files with the site on the server

I’ve never come across this before and am at a loss - what am I missing?
