How to install a plugin in WordPress
To install a new plugin, select Plugins > Add New in WP Administration. Another way is to click "Modules" in the administration and then "Add new" at the top of the page. Clicking the "Add" button will open a new list of plugins from the official WordPress.org website. You can filter this list by "Recommended", "Popular" or "Favorites" modules. You can also find a specific WordPress plugin here.
You can view the capabilities of each module by clicking on the name or the "Details" link. A window with the functions offered by the module will open. You will also find information about the author and when it was last updated. Click Install Now to install the selected module.
Activating the plugin
Then you need to activate each module. For this step, use the "Activate" button. For some modules, you will also find settings that you will need to configure. The installed module will appear in the list of plugins on your site.
If there is an update for one of the modules you are using, WordPress will notify you by displaying a number next to “Modules” in the menu. In the list of extensions, you can also find an update message with an update link. The system will notify you of a successful update.
Before updating the module, make sure that this step does not affect the functionality of the page. After the update, make sure the module is working correctly.
Deactivation and removal
You can find a link to deactivate the plugin in the list of modules. To deactivate the plugin, click Deactivate. If you have a module on your site that is disabled and you haven't used it for a long time, you need to remove it. To do this, click the "Uninstall" link under the name of the module.
