PHP Warning: chmod() on class-wp-filesystem-direct.php about slickstack

[jessuppi]

Thanks @gbozzetti

This was possibly a temporary issue while we were optimizing our ss-perms (reset permissions) core script. Please let me know if you are still seeing any permissions-related errors?

From my understanding, most similar permissions errors given by class-wp-filesystem-direct.php are due to file ownership conflicts, but this should not be an issue with SlickStack default permissions:
