[Koha] software error message - authorities

[Elaine Bradtke]

I tried to delete an authority record with 0 biblios and got the
following message:
Undefined subroutine &C4::AuthoritiesMarc::prepare called at
/usr/share/koha/lib/C4/AuthoritiesMarc.pm line 720.

We're running 3.2.5.
I can't seem to delete any authorities at the moment.
Any idea what this means, or how we can fix it?
