Hi Paul Today you wrote:

There is no such system preference in Koha.

Any ideas?
There seems to be something wrong... When Plack is already running the output should look as follows (as on my Koha demo installation with instance "koha" and Plack running): $ sudo koha-plack --enable koha Plack already enabled for koha OPAC Plack already enabled for koha Intranet $ sudo koha-plack --start koha Error: Plack already running for koha: failed! $ sudo koha-plack --status koha Plack running for koha:. The following shows the instances with Plack enabled and the instances with Plack disabled: $ sudo koha-list --plack koha $ sudo koha-list --noplack After enabling and starting Plack try restarting the Apache HTTP Server, according to some mailinglist threads it seems to have helped some in the past. Thus: $ sudo koha-plack --enable koha $ sudo koha-plack --start koha $ sudo systemctl restart apache2 And again: Have you checked the log files in directory "/var/log/koha/instancename"? There should be various logfile names starting with plack... Best wishes: Michael -- Geschäftsführer · Diplombibliothekar BBS, Informatiker eidg.

Have you checked the log files in directory "/var/log/koha"?
Have you set up Plack as described here?

Hope this helps.

Hi Paul, you might want to also check the existence and content of the following files: /etc/koha/apache-shared-intranet-plack.conf /etc/koha/apache-shared-opac-plack.conf as well as their references within the file of this instance-based name: /etc/apache2/sites-enabled/library.conf If you somehow wound up with an Apache configuration that isn't being managed by the Koha tools, then it could be interfering.
