You can access the list of Plugins of your P4 instance from your Admin Dashboard > Plugins.


  1. Each plugin MUST pass the security review before being installed. More info at the bottom of the page
  2. DO NOT Enable automatic updates of any plugin. Updates are done via Composer for all P4 sites.

Are you a Dev? Please read me

Installation and updates of plugins is happening via the composer scripts. All the plugins that are present in all installations are defined in the common composer file.

Additionally, plugins that are installed only on a specific P4 site is defined in the composer file for that site. For example, Loco Translate is only installed on the handbook site, and is defined in the handbook composer file.

Open source plugins are being pulled from . To add a plugin, you have to find the correct wpackagist record, copy the line and insert it in the composer file as the loco translate example above.

Plugins NOT used

SEO plugins

P4 has no SEO plugin installed or recommended.

SEO plugins do a lot of things, some of which are not even things that should be done (yes, trying to “trick” Google into thinking that a page is something different than it is, by modifying the title or the metadata for browser or search engines is a “disaster waiting to happen”).

We have identified several features that are also being offered by some SEO plugins, such as open graph data (PLANET-1888, released in v1.8 , handled by the p4 master theme) or write beautiful URLs (using core WP functionality with small taxonomy modifications handled in our master theme PLANET-1879, released in v1.9 ).

Our choice of operation is not “There is a plugin, let’s install it and see what it does”, but “We need feature A, let’s find the best way to deliver its functionality”.

The P4 Plugin review process

The philosophy of adding plugins to a P4 site can be summarized in the following:

We have described a process that should be followed every time a plugin is considered.

1) Decide on the features you want

2) Investigate if these can be done by WordPress core

3) If not, investigate what 3rd party plugins exist, and a do a functional fit analysis

4) Do a security analysis of the selected plugins, including reputation, maintenance history, and code analysis

5) Install them on the test server and do a thorough testing (using both automatic testing and manual testing) to see if they create problems in other areas of P4.

6) Get them installed on the relevant site, by having them being added to the relevant composer file

We will have to repeat that you must be very very very careful before adding plugins to your site, as you are endangering the whole greenpeace domain.

In case we find that you have installed a plugin that creates security issues or that it has been added without correct documentation (Functional fit and security analysis), we will remove it immediately to safeguard the rest of the website. 

In cases where a plugin is added only to one site and not to the planet4 core, there is an extra complication that needs to be taken in to serious consideration:
When a plugin is installed on a site only, independently from the planet4 core, then the sites owner/administrators (The NRO or the campaign, or the project team) has to take the responsibility for that plugin or extra code forever.
If the plugin has a security update, they need to update it. (Or if they don’t know how, to hire a developer or an agency to keep it up to date). Or we (the planet4 team) will have to remove it from the platform (even if this means broken functionality). So, any such plugin that you add, creates a future responsibility (and quite possibly a budget expenditure) for the owners/administrators of the site. Additionally, if your plugin at some point is not compatible with the core application or the infrastructure, it is not the Planet4 team’s responsibility to make the core compatible with your extra plugins.
