I am running multisite with BuddyPress plugin. I've network enabled "Custom Community" theme via the Network Admin.
If I go to the dashboard of any of the "sub" sites, is see the following error:
ERROR: The themes directory is either empty or doesn’t exist. Please check your installation.
I've attempted to network enable other themes - same issue. And the front end of the sites just loads a blank/white page.
Any help? Thank you,
