I’ve lost the backwpup menu item as well. I’ve deactivated/activated and deleted/reinstalled to no avail. I’ve even deactivated all the plugins that could be causing a conflict (database caching, etc..) Nothing works. /wp-admin/admin.php?page=backwpupjobs gives me a page not found.
Btw, I am a superadmin and hosting on AWS with my own nginx ami.
Any other ideas?
