Re: fatal error: members and groups.
I had that but it was because I loaded buddypress as a subfolder
“Move contents of the extracted folder into â€œwp-content/mu-pluginsâ€. All files should be in the root of â€œmu-pluginsâ€ not in a sub folder. For example, â€œmu-plugins/bp-core.phpâ€ NOT â€œmu-plugins/buddypress/bp-core.phpâ€”
Once I did that it was fine
