[Koha] Problem with Check expiration in Serials

[Elaine Bradtke]

​We're running 3.20.7 and just getting around to testing out some of the
features in the Serials module. We set up a dummy record to try things like
notices, etc. and when I clicked on Check Expiration all I got was an error
message.​

Any idea what the following means?  I
​ get the gist of it - something's missing somewhere. I​
can't find any system preferences that look remotely
​like they might address this. There really is only one 'branch' in our
system.

checkexpiration.pl aborted due to compilation errors.
