WordPress.com allows plugin installation only for websites in the WordPress.com Business plan. If you have a free WordPress.com website or a paid account other than business, you can’t install plugins and can’t use Dev4Press plugins.

If you have a WordPress.com Business plan, you can install and use most Dev4Press plugins, with the exception of plugins made for a multisite network. Currently, CoreSecurity is the only plugin that can’t be used on WordPress.com. However, all the plugins that do work can be used from the WP Admin panel in WordPress.com; they can’t integrate into WordPress.com’s own dashboard or editor.

However, due to the way WordPress.com works and the fact that it is a very closed system, we can’t provide support related to the server setup and cannot guarantee that all our plugins will work with WordPress.com as expected.
