Re: 404 /blog /members etc… RC2 WPMU 2.7.1
Okay, since we’ve had a few people make this mistake I need to ask this just in case. Everyone in this thread who is having 404 issues is running BuddyPress with WPMU and not the single-user version of WordPress, correct?
This means downloading WordPress from here: https://mu.wordpress.org/download/
Running WPMU, ran automatic upgrade to 2.7.1 prior to installing BP
Were you running WPMu 2.7.1-beta1 before upgrading?
If so, you cannot upgrade from beta1 to public 2.7.1 using the automatic upgrade feature. This is because the upgrade script “sees” WPMU 2.7.1 = WPMU 2.7.1, meaning it does not upgrade you from beta1 since it thinks you are already running 2.7.1.
So, you must manually upgrade WPMU following these instructions: https://codex.wordpress.org/Upgrading_WPMU
