I see this was touched upon in a thread six months ago (
www.joomlapolis.com/forum/277-cbsubs-gpl-support/224266-acl-manager-and-cbsubs-creates-orphans#240606
) but it doesn't seem to have a resolution.
I see it's strongly recommended on Joomla.org to use ACL manager before attempting a 2.5.x-to-3.3.3 Joomla upgrade. But ACL manager is stalled on a lot of CBsubs items - and I get the feeling that nuking these with ACL manager is going to harm CBsubs.
Yes, or no??
