Subdomain not reading modules or themes folder under sites/all/

Question

I have a site set up with drupal, everything going fine. I then added a subdomain, and that too was fine until I went to enable a custom theme that was under the sites/all/themes folder. The theme does not show properly in the admin panel (no thumbnail), and when activated, the site appears to have no structure at all.

The theme I am trying to use works flawlessly on my other sites, so the theme itself is not a problem. I noticed the same happens with modules under that all/ folder. It is able to use anything under the root themes and modules folder however.

So something is preventing it from properly loading/reading the sites/all/ folder. Dumping everything into the core folder is not ideal of course, but I can't figure out the problem.

Edit: RESOLVED! Somehow an htaccess file got into the sites folder with a redirect in it. Causing just the subdomain to not see the subfolders properly, only root.

If the themes and modules under sites/all are unavailable for both sites - the main site and your subdomain - then the problem may be around accessibility of the folder.

Regardless of the user account you use to access the site, it's almost certain that the website server itself (whether Apache, IIS or Xyz) runs as a different account. If that account doesn't have rights to scan for, and read, files under sites/all then they won't show up.

Compare the permissions (and user/group details, if running on a Unix server) between your regular modules directory and sites/all to find any differences, and fix any you find.
