How do I enable and disable Roundcube plugins?

This article covers how to enable and disable plugins, but does not cover how to configure any specific plugins.

IMPORTANT: A misconfigured plugin could cause roundcube to fail. Always backup before making changes.

To see a list of your available plugins

ls /usr/local/topicdesk/roundcube/WebApp/plugins/
Let’s be friendly and enable: emoticons

Plugins are enabled/disabled in the roundcube configuration file. We’ll use pico to edit the file.

sudo pico /usr/local/topicdesk/roundcube/WebApp/config/

Look for the plugin array, it will look something like this
$config['plugins'] = array('image_paster','html5_notifier','chbox','carddav','managesieve');

To enable show_additional_headers add it to the array, so it looks like this:
$config['plugins'] = array('image_paster','html5_notifier','chbox','carddav','managesieve','emoticons');

Logout and Login to Roundcube and now you have:

Roundcube WebMail Emoticons

To disable plugins

If a plugin causes roundcube to fail or you simply don’t need it – you remove the plugin from the array.

sudo pico /usr/local/topicdesk/roundcube/WebApp/config/
