I should probably have mentioned that this is a BuddyBoss installation. Here’s what’s available from the permalink settings. The slug for the discussions list view is the one that seems to be missing . . .
Yeah I’m aware of that. I also wasn’t asking for support with the BuddyBoss platform. I actually thought there’d be a fairly simple way to rename the slug–completely independent from it, because I don’t believe it’s BuddyBoss-related at all. Thanks anyway.
