How to Properly Uninstall a WordPress Plugin: A Beginner‘s Guide (2023)

Hey there, WordPress user! Is your site feeling a little sluggish or cluttered? Chances are, it might be time to do some plugin housekeeping.

Navi.

As a WordPress expert, I‘ve seen firsthand how unused plugins can really bog a site down over time if not properly managed. In fact, a study by WP Engine found that 50% of WordPress sites have at least 10 plugins installed, and 20% have over 20 plugins (source: WP Engine Plugin Madness Report). That‘s a lot of potential bloat!

But never fear, uninstalling plugins you no longer need is a quick win for keeping your site lean and mean. In this beginner-friendly guide, I‘ll walk you through exactly how to properly uninstall a WordPress plugin step-by-step, based on my years of experience. We‘ll also dive into some best practices and troubleshooting tips to keep your site running smoothly.

By the end of this guide, you‘ll be a plugin management pro, ready to confidently clean up your WordPress site. Let‘s get started!

Why You Should Uninstall Plugins You Don‘t Need

I get it, trying out new plugins is fun! It‘s easy to get carried away installing all sorts of shiny new toys on your WordPress site. But over time, all those deactivated plugins start to add up and can really slow your site down.

Here are a few key reasons why I always recommend uninstalling WordPress plugins you‘re no longer actively using:

Improved site speed and performance. Every installed plugin, even deactivated ones, adds some overhead that can impact your page load times. Uninstalling frees up those resources.
Better site security. Outdated or poorly-maintained plugins are a common target for hackers looking to exploit vulnerabilities. Fewer plugins means less risk.
Easier troubleshooting. The more plugins you have, the harder it is to pinpoint conflicts or issues. Streamlining your plugin stack makes diagnostics simpler.
Cleaner database. Many plugins create their own database tables that can bloat your database and backups, even when deactivated. Removing them tidies things up.

In short, keeping your plugins lean is well worth the bit of regular housekeeping. It‘s one of the simplest ways to ensure your WordPress site stays speedy, secure, and problem-free.

How to Properly and Safely Uninstall a WordPress Plugin

Alright, let‘s dive into the step-by-step process for uninstalling a WordPress plugin the right way. The good news is, it‘s actually quite simple!

Important note: Before uninstalling any plugin, always make a complete backup of your WordPress site, including your database. This allows you to quickly restore if anything goes wrong.

Here‘s how to uninstall a plugin via your wp-admin dashboard:

Log in to your WordPress admin area and go to "Plugins" in the left sidebar.
Find the plugin you want to uninstall in the plugins list.
If the plugin is currently active, click "Deactivate" to deactivate it first.
Once deactivated, click the "Delete" link that appears below the plugin name.
Click "OK" on the confirmation prompt to complete the uninstallation.

WordPress will then remove all the plugin‘s files and database tables, and you‘re done! Pretty painless, right?

In most cases, this process will fully remove all traces of the plugin. However, there are a few exceptions to be aware of:

Some plugins store additional files in non-standard locations like /wp-content/uploads. These are not always automatically removed during uninstallation.
Certain plugins may leave behind some orphaned database tables after uninstalling.

If you want to be 100% thorough, you can optionally take a couple extra steps to clean up any potential stragglers.

To remove leftover plugin files, connect to your site via FTP and browse to the relevant non-standard directories (like /wp-content/uploads). Delete any folders relating to the uninstalled plugin.

To clean up orphaned database tables, you‘ll need to access your database directly via a tool like phpMyAdmin:

Log in to phpMyAdmin via your hosting panel.
Select your WordPress database.
Look for any tables that contain the uninstalled plugin‘s name or prefix.
Select those tables and choose "Drop" from the dropdown to delete them.

Caution: Be very careful when modifying your WordPress database directly. Backup first and only delete tables you‘re 100% sure belong to the plugin in question.

These extra cleanup steps are not necessary for most plugins. But if you really want to be thorough, it‘s good to know how.

WordPress Plugin Management Best Practices

Properly uninstalling plugins is just one part of overall plugin management. Based on my experience working with countless WordPress sites, here are some key best practices I recommend for keeping your plugin stack tidy and trouble-free:

1. Be selective about the plugins you install

There are over 50,000 free plugins in the WordPress.org repository alone, plus countless more premium options. It‘s tempting to try them all, but practicing some restraint goes a long way.

Only install plugins from reputable sources that are regularly updated and well-reviewed. Avoid anything that looks outdated, spammy, or suspicious. And most importantly, only keep plugins that serve a clear purpose for your particular site.

2. Keep your plugins up-to-date

One of the most important things you can do for your WordPress site is keep everything updated. That includes your plugins!

Developers frequently release updates that patch security issues, fix bugs, and add new features. Failing to promptly install these updates leaves you vulnerable to issues down the road.

I recommend configuring auto-updates for your plugins when possible, so you don‘t have to remember to check manually. However, it‘s still a good idea to test updates on a staging site when you can, just to make sure there are no conflicts or incompatibilities.

3. Regularly audit and clean up your plugins

Every few months, set aside some time to audit your plugins and uninstall any stragglers you no longer need. Some people use the "1 in, 1 out" rule to keep bloat under control – for every new plugin you install, try to find one to remove.

While there‘s no hard and fast rule for how many plugins is "too many", a good general guideline is to aim for under 20 whenever possible. Of course, some sites may require more – just be judicious and proactive about cleanup.

Here‘s a quick checklist for auditing your plugin list:

Is it active and serving a clear purpose? If not, remove it!
Is it performing a function that could be better handled by custom code or your theme? Consolidate and simplify.
Is it redundant with other plugins or tools you‘re using? Aim to minimize overlap.
Is it from a reputable source, well-maintained, and regularly updated? If not, consider finding an alternative.

Removing plugins is much easier than dealing with a slow, bogged-down site!

4. Use a staging site to test new plugins

Before installing a new plugin on your live production site, it‘s always best to test drive it first on a staging site. This allows you to safely evaluate the plugin‘s functionality and performance in a sandboxed environment.

Some key things to test:

Does the plugin play nicely with your current WordPress configuration and other plugins?
Does it add any noticeable performance overhead or slow down your page loads?
Are there any unexpected errors or conflicts?

Only push the plugin to your live site once you‘ve fully vetted it and confirmed it doesn‘t have any adverse effects.

5. Choose lightweight, well-coded plugins

Not all plugins are created equal! Even if two plugins accomplish the same basic task, one may add way more bloat and slowdown than the other.

Whenever possible, opt for lightweight, well-coded plugins (often from experienced developers or reputable companies). Some tips for gauging plugin quality and performance:

Check the plugin‘s reviews and support forums for performance-related complaints
Test the plugin‘s impact on speed using a tool like Query Monitor or New Relic
Look at the plugin‘s code (if you‘re able) to ensure it follows WordPress coding best practices
Avoid "kitchen sink" mega-plugins that try to do too many things. Opt for plugins that do one thing really well.

In general, less is more when it comes to WordPress plugins. By being selective and prioritizing performance, you‘ll avoid one of the most common culprits of WordPress slowness.

When Uninstalling Goes Wrong: Troubleshooting Tips

While most of the time, uninstalling a WordPress plugin is a straightforward process, occasionally you may run into some hiccups. Don‘t panic – here are some common issues and how to resolve them:

White Screen of Death or Errors After Uninstalling

Seeing a blank white screen or error message after uninstalling a plugin? This often indicates a PHP error or conflict caused by removing the plugin. Here‘s how to troubleshoot:

Connect to your site via FTP.
Rename your /wp-content/plugins directory to something like /plugins-old. This will deactivate all your plugins at once.
Rename the directory back to /wp-content/plugins.
Reactivate your plugins one-by-one until you encounter the error. The last reactivated plugin is likely the culprit.
Replace that plugin with an alternative or contact the plugin author for guidance.

Broken Shortcodes or Weird Formatting

Some plugins use shortcodes to embed content throughout your site. If you uninstall one of these plugins without first removing the shortcodes, you may see strange formatting issues.

To fix this, you‘ll need to find and remove all instances of the plugin‘s shortcodes from your content. You can use a search/replace tool or manually edit each post. If the plugin added content you want to keep, you‘ll need to replace the shortcodes with standard formatting or HTML.

Missing Functionality or Changed Appearance

Sometimes uninstalling a plugin can have unintended side effects on your site‘s functionality or appearance, especially if your theme relied on that plugin in some way.

If you notice something not working correctly after uninstalling a plugin, consider the following:

Did the plugin provide a critical function that you still need? If so, you may need to find an alternative solution to replace it.
Check the plugin‘s documentation to see if there are any special uninstallation steps or considerations.
Test your site thoroughly and review your theme settings, widgets, etc. to ensure everything is working as expected.

Wrapping Up

Whew, that was a lot of information! I hope this guide has given you the knowledge and confidence to properly manage your WordPress plugins and keep your site running like a well-oiled machine.

Remember, uninstalling plugins you don‘t need is one of the simplest and most impactful ways to improve your WordPress site‘s performance, security, and manageability. By staying on top of plugin housekeeping, you‘ll save yourself a lot of headaches down the road.
