[Koha] koha stop working after enabling plack

Fri Aug 17 16:01:56 NZST 2018

Hi Tomas

Thanks for your answer. This is the result of the pm commnad:

aco at Celacp:~$
aco at Celacp:~$ pmvers Mojolicious
7.21
aco at Celacp:~$ pmvers JSON::Validator
0.97
aco at Celacp:~$

aco at Celacp:~$ sudo more /etc/apt/sources.list.d/koha.list
deb http://debian.koha-community.org/koha stable main
aco at Celacp:~$

I do not want to change the apt source version to 17.05  main since I need
to first save the koha customisations we made.

does this be the cause of the plack error?

Regards,

Alvaro
