When running koha-plack --enable, the script assumes that there is already a commented line that includes the plack configuration in the apache virtual host's config of the instance : (from /usr/sbin/koha-plack line 148) : sed -i 's:^\s*#\(\s*Include /etc/koha/apache-shared-opac-plack.conf\)$:\1:' "$instancefile" sed -i 's:^\s*#\(\s*Include /etc/koha/apache-shared-intranet-plack.conf\)$:\1:' "$instancefile" For old fashioned installs this is not always the case. In my config (we've set up koha 3 years ago) i had to put the line directly in the apache virtual host config. Since the included files use the ${instance} variable, i had to define that variable as well : Define instance myinstancename It is possible to find where the "/etc/koha/apache-shared-{opac,intranet}.conf" files are included and add the two relevant lines : --- a/koha-plack +++ b/koha-plack @@ -144,9 +144,9 @@ enable_plack() local instancefile=$(get_apache_config_for "$instancename") if ! is_plack_enabled $instancename; then - # Uncomment the plack related lines for OPAC and intranet - sed -i 's:^\s*#\(\s*Include /etc/koha/apache-shared-opac-plack.conf\)$:\1:' "$instancefile" - sed -i 's:^\s*#\(\s*Include /etc/koha/apache-shared-intranet-plack.conf\)$:\1:' "$instancefile" + # Add the plack related lines for OPAC and intranet and define the instance name in vhost + sed -i "s:^\(\s*\)\(Include /etc/koha/apache-shared-opac.conf\):\1\2\n\1Define instance $instancename\n\1Include /etc/koha/apache-shared-opac-plack.conf:" "$instancefile" + sed -i "s:^\(\s*\)\(Include /etc/koha/apache-shared-intranet.conf\):\1\2\n\1Define instance $instancename\n\1Include /etc/koha/apache-shared-intranet-plack.conf:" "$instancefile" [ "${quiet}" != "yes" ] && warn "Plack enabled for ${instancename}" return 0 else Regards, Philippe K. https://laretive.info
