Can't get sidebar to open

I can no longer get the mutt-ng sidebar to open with either builds 496
or 499.  It defaults to open when I start mutt-ng (although no folders
are displayed) and I close it with <shift>b per my .muttngrc which I
attached.  However, the same key sequence does not display the sidebar.

A neighbor came to Nasrudin, asking to borrow his donkey.  "It is out
on loan," the teacher replied.  At that moment, the donkey brayed
loudly inside the stable.  "But I can hear it bray, over there."  "Whom
do you believe," asked Nasrudin, "me or a donkey?"
