I'm running 4.7.27 and regardless of what I set the $civicrm_root to, the hints in resource URL and file path setting pages give quite unrelated values for civicrm.root. I am also unable to set the resource URL to anything but the prefilled value (editing it and submitting does nothing).
Consequently it looks like some override is at work. However, I've checked the civicrm.settings.php many times and I'm unable to find such an override.
What could be causing this? Everything displays fine, except for loading of the CKEditor js-files. But the fact that editing civicrm.settings.php doesn't do anything scares me. I've verified that the file is indeed the correct one (removing it breaks the site), and that even removing the $civicrm_root entirely does nothing.
From the settings:
global $civicrm_root;
$civicrm_root = '/foo/www/sites/abc.foo.se/current/web/app/plugins/civicrm/civicrm/';
if (!defined('CIVICRM_TEMPLATE_COMPILEDIR')) {
define( 'CIVICRM_TEMPLATE_COMPILEDIR', '/foo/www/sites/abc.foo.se/shared/uploads/civicrm/templates_c/');
}
