Then i was just playing around,

chown librenms:www-data devices_relationships.cache (didn’t work)
chown www-data:www-data devices_relationships.cache (worked, can now create device group)

changed back:

chown librenms:www-data devices_relationships.cache (worked , didn’t before)
chown librenms:librenms devices_relationships.cache (works again, don’t see what changed)

Hope that might help :stuck_out_tongue:
