Plugin System

Koha’s Plugin System allows for you to add additional tools and reports to Koha that are specific to your library. Plugins are installed by uploading KPZ ( Koha Plugin Zip ) packages. A KPZ file is just a zip file containing the perl files, template files, and any other files necessary to make the plugin work.

The plugin system needs to be turned on by a system administrator.

Set up

To set up the Koha plugin system you must first make some changes to your install.

  • Change <enable_plugins>0</enable_plugins> to <enable_plugins>1</enable_plugins> in your koha-conf.xml file
  • Restart your webserver

Once set up is complete you will need to alter your UseKohaPlugins system preference. On the Tools page you will see the Tools Plugins and on the Reports page you will see the Reports Plugins.

About Koha

The ‘About Koha’ area will give you important server information as well as general information about Koha.

  • Get there: More > About Koha

Server Information

Under the ‘Server Information’ tab you will find information about the Koha version and the machine you have installed Koha on. This information is very important for debugging problems. When reporting issues to your support provider or to the various other support avenues (mailing lists, chat room, etc), it’s always good to give the information from this screen. The time zone is handled via Koha or server configuration. For more information how to specify time zones per instance, see


Perl Modules

In order to take advantage of all of the functionalities of Koha, you will need to keep your Perl modules up to date. The ‘Perl Modules’ tab will show you all of the modules required by Koha, the version you have installed and whether you need to upgrade certain modules.


Items listed in bold are required by Koha, items highlighted in red are missing completely and items highlighted in yellow simply need to be upgraded.

System Information

This tab will provide you with warnings if you are using system preferences that have since been deprecated or system preferences that you have set without other required preferences
