Re: Upgrading BP and MU.
This is likely related to a major flaw in MU 2.8.1 that will hopefully be fixed soon where a lot of the upgrade functionality is broken or otherwise off. I was able to upgrade to 2.8.1 using the automatic upgrade but it’s still telling me to upgrade. The same goes for plugins, I’ve upgraded them but they still say there’s updates available plus there’s no prompt to upgrade when new plugin versions like BuddyPress 1.0.3 is released.
Manual upgrade is the only option I know of right now.
