[Koha] Error in "Libraries and groups"

[Italo Brasileiro]

Hi everyone.
I'm using Koha version 18.05.04.000. I'm having a problem when accessing
the "Libraries and groups" topic on the Koha settings page. The following
error message is displayed:





















*Software error:Template process failed: undef error - The method
