All those files (listed in Chrome's Console w/ errors) do exist, permissions are 644... what am I missing? This started after upgrading to 4.7.21 and Joomla 3.7.3.
Any pointers greatly appreciated : )
This was caused by [civicrm.root] using https://www.mydomain.com/components/com_civicrm/civicrm/
while it should be using http://www.example.com/administrator/components/com_civicrm/civicrm/
The $civicrm_root variable is correct in both civicrm.settings.php files so I'm really confused why CiviCRM cannot pull the civicrm.root variable correctly.
