I’ve just activated BP Activity Block Editor (https://github.com/buddypress/bp-activity-block-editor) on my multisite, it stops me accessing ‘Aactivity’ in admin panel. The error msg says I am not allowed to access the page. Given that my account is for superadmin, I doubt I have any access right issue, but as far as I remember, the error msg appears when the user has no access rights for the function.

My guess is that it is due to multisite setting, but I do not have much clue.
