Wrong compiled [civicrm.files] variable in Resources URL
This usually happens when your site directory is using symbolic link. To fix the variables you will need to make sure that the docroot specified in apache/ngnix config should match exactly with $civicrm_root and CIVICRM_TEMPLATE_COMPILEDIR in civicrm.settings.php. 

Try updating if its different and clear CiviCRM cache.
