[Koha] Batch check outs timing out after upgrade and migration

[Lennon Mazonde]

Hi Matthew,

1. To enable Plack you need to run

     sudo koha-plack --enable instancename

then

     sudo koha-plack --start  instancename

2. To resolve the admin email warning, go to Home  > Administration  > 
System preferences > Interface options > KohaAdminEmailAddress and enter 
your admin email. You may have to do some additional configuration on 
your back-end server to setup an email server such as Postfix to enable 
your Koha instance to send out emails.

I hope this helps!
