WordPress® offers a large number of plugins to add functionality to your Website. They range from anti-spam comment filters to helping you build a small-scale social network.
How you manage and use the plugin depends on its developer. You can view all of the currently installed plugins by clicking Plugins on the menu.
Some WordPress plugins can slow your Website's performance. Deactivating your plugins and then testing your Website's performance again can help you troubleshoot. For more information, see Troubleshooting Common Issues in WordPress.
