Just updated classifieds and directory, and both now saying permission denied when I try to access

I've just updated the classifieds and directory plugins and now both these sections of my site AND all other sections are giving the permission denied notification again like last week. Don't know whether this issue is connected or not? This is last weeks issue which fixed itself but I've no idea how? https://premium.wpmudev.org/forums/topic/why-is-this-page-showing-permission-denied Please can someone look urgently?
