After installing this module, I see the following two messages on the status page:
- Adv CSS/JS Agg - CSS Path is not setup correctly. CSS directory is not created or writable.
- Adv CSS/JS Agg - JS Path is not setup correctly. JS directory is not created or writable.
However, the permissions on the Drupal files directory looks fine, and the main Drupal file system reports "Writable (public download method)".
So is there really a problem here, or are things being reported incorrectly?
