In this tutorial you will learn the importance of keeping your WordPress plugins up-to-date, how to easily upgrade and delete plugins from your site, and some great tips to help you better manage your plugins if you need to run multiple WordPress sites or blogs.
Why Plugins Need Upgrading
The WordPress software is constantly updated (about every three to four months) to fix bugs and address security issues and vulnerabilities discovered in earlier software releases, as well as to improve existing features or introduce new functionality to WordPress users.
Depending on how many plugins you use on your site, you can expect to see at least some new new update notifications for WordPress plugins each time a new WordPress version is released.
The reason for this, is because most WordPress plugins are created by external developers, so sometimes code in the new WordPress version conflicts with plugins that were developed and tested with a previous version. Whenever this happens, problems can sometimes occur.
Fortunately, most WordPress plugin developers (and the WordPress developer community itself) are fairly proactive when it comes to making sure that plugins get updated when a new version of WordPress is released (if updating is required). All you need to do on your end, is keep your plugins up-to-date, which, as you will soon discover, is really simple and easy to do.
Keeping your WordPress plugins up-to-date and deleting old plugins you no longer need is part of good WordPress site management and helps to avoid any potential problems and errors.
The step-by-step tutorial below explains how to update and delete plugins in WordPress without requiring web coding knowledge.
How To Automatically Upgrade And Delete Plugins – Tutorial
WordPress has a few methods to let you know when plugins on your site need to be updated.
For example, you can see ‘at a glance’ how many plugins need to be updated as soon as you log into your Administration site by looking at the main “Plugins” menu.
In the example below, 9 WordPress plugins have older versions that need updating …
You can also check how many plugins need updating from your WordPress Toolbar (as shown below, a number of plugins require updating) …
The Plugins screen (Plugins > Installed Plugins) also lets you know which plugins need updating …
As well as providing information about plugins that have available updates, the Plugins section provides links to the plugin download pages and gives you the option to update your plugins instantly …
Let’s start by showing you how to update one WordPress plugin at a time.
Upgrading WordPress Plugins Individually
We strongly recommend performing a full backup of your website before making any updates to your website or blog.
In your dashboard menu, go to Plugins > Installed Plugins …
The “Plugins” screen will display in your browser. This list of plugins can be quite long depending on how many plugins you have installed in your site …

Additional Info:
If you have too many plugins and would like to make this section more manageable, then click on the Screen Options tab at the top of your Plugins page and enter a smaller number of items per page (all plugins show up on the screen by default, i.e. “999”), then click the ‘Apply’ button …
Your Plugins area will now be made more manageable with a page scrolling feature added. You can find an installed plugin by scrolling through the pages or using the “Search” field …
You will see information about plugins in different backgrounds depending on the status of your plugins (inactive vs. active and up-to-date vs. out-of-date) …
Plugins in need of upgrading show the following notification message: “There is a new version of [Insert Plugin Name] available” …
Select the plugin that needs to be updated and click on the update now link …
WordPress provides streamlined plugin updates, so that the process of updating your plugins happens with just “one click” without leaving your Plugins area …
Repeat this process for any other plugins on your site that need to be updated, or see the section below if you have many plugins that are out-of-date and would like to update all plugins in one simple operation.

Useful Management Tools For WP Plugins

Managing WordPress Plugins On Multiple Sites
As discussed earlier, when plugin updates are released, the best practice is to update the plugin as soon as possible to its latest version.
What if you run multiple WordPress sites using the same plugin?
Typically, you would need to log in to every site individually and update the plugin manually from the site’s admin dashboard.
If you manage or plan to manage multiple sites, this process can become very time-consuming, especially as plugins get updated quite often.
If you manage multiple WordPress sites, you can install, update, and delete multiple plugins on all your sites automatically and simultaneously using WordPress site management tools, like the one below:
WPMU DEV’s The Hub

The Hub lets you manage unlimited WordPress sites easily and effectively from one central command center.
The Updates section of The Hub shows you exactly what needs updating on each of your managed site(s), including plugins, themes, and core software updates.

The Hub’s Updates features display how many outdated components need updating on your site(s).
You can choose to either update all your plugins at once or update them individually with just a few clicks. Best of all, you don’t need to log into every site separately to perform your plugin updates.

Update everything at once or perform individual updates directly in The Hub with a few clicks.
This can be a real time-saver when managing multiple WordPress sites, especially when WordPress releases a new version and you have to update many plugins and themes to prevent potential issues from happening.
