The Business Plan gives you access to tens of thousands of plugins in the WordPress ecosystem. Plugins give your site superpowers, helping you turn your dreams into reality.

In many cases, we’ve already provided identical or superior functionality directly via our interface or infrastructure, so installing additional plugins wouldn’t impact your site’s performance or features, and could negatively affect it instead.

We are not implying that all plugins on this page are bad, but by disallowing these plugins we wish to ensure a scalable and efficient hosting environment for all our customers.

We’ve spent a lot of time building in features and functionality to every WordPress.com site, so if you have a specific feature or functionality you’re trying to add to your site, get in touch with Support and you may discover that it’s already available without a plugin!

If you want to use any of the plugins on the list below please contact us and we’ll help you find alternatives.

Automated Content Plugins

We’ve found that these sorts of plugins are not a good fit for sites hosted here at WordPress.com and ask that you refrain from using them as not only do they place unnecessary loads on our infrastructure, automated posting is often seen as spam and is generally unwanted.

  • Octolooks Scrapes
  • RSS Feed to Post
  • Woozone/WZone
  • WordAi Aggregator
  • WP Automatic
  • WPRobot5
  • WP Inject
  • WP RSS Aggregator

Using ABSPATH? Read on...

Some themes and plugins break on our platform due to incorrect usage of the ABSPATH variable in requiring files or writing into folders.

You may not use ABSPATH on our platform, as this points to the core WordPress folder, unless you are requiring a core file.  Instead, you must use WP_CONTENT_DIR, which is defined on our system as /htdocs/wp-content.

Such that when requiring a file, it would look like:

require_once( WP_CONTENT_DIR . '/plugins/plugin-stuff/stuffs.php' );

Otherwise, if on other hosting platforms WP_CONTENT_DIR wasn’t defined, it would default to:

ABSPATH . 'wp-content'

My plugin says I need ionCube Loader, what's that, and do I have it?

The ionCube Loader is a PHP module used to hide and obfuscate PHP code.  Some plugins such as AliDropShip require this to be installed on your site’s server to function. At the present time we do not run ionCube on our servers. As a result, any plugins that rely on it will not function on WordPress.com-hosted sites.

My plugin says the database doesn't support a character set. What do I do?

Some plugins, notably Convertkit, require a particular database character set, such as UTF-8. Sites on WordPress.com use Latin1 as a character set. If a plugin requires a different character set, please reach out to the plugin developers for an alternative solution.
