How to properly delete wordpress plugin manually from backend

disable wordpress plugins

With over 55,000 plugins, wordpress is the most preferred platform for blogging. Having said that, there’s a plugin for every need. At times, you test a plugin and find it inefficient for your need. So you deactivate it and delete it. However, deactivating it alone cannot be enough. There are some residual files created by the plugin left in the database. You should be deleting those files too.
Furthermore, there are chances you’d install an irrelevant plugin for testing purpose and end up losing access to the admin area. In that case, how’d you delete wordpress plugin? You will get to know exactly this herewith.

This post is for those who have installed such plugins and want to delete wordpress plugin. In this post, I will touch the following common questions that’d clear all your doubts:

  • Why you need to uninstall wordpress plugin
  • Difference between uninstalling and deactivating a wordpress plugin
  • How to uninstall a wordpress plugin
  • How to remove extra files added by a wordpress plugin
  • Cleaning wordpress database (delete wordpress plugin from the database)

So let’s begin without any delay.

Why you even need to uninstall wordpress plugin? What is the difference between uninstalling and deactivating a plugin

The main reason behind this post is the fact that I lost access to my wordpress admin area upon installing a wordpress plugin that clashed with my current wordpress settings. This resulted in losing access to the wordpress admin area. I had no other option other than to delete wordpress plugin from the database. And that’s what I did.

However, a lot of times you and me try and test a lot of wordpress plugins for various needs. But we end up finding it not to the mark per our requirement. Hence, we simply deactivate it and/or even delete it. But that is not all you should do.

Not all plugins have an auto-clean mechanism for various reasons. Which shall be discussed in subsequent sections. Now, if you disable/deactivate a plugin, it still occupies space in your database. This means it will affect your site loading speed, not in a good way.

Furthermore, if you keep unnecessary files on your site it will also increase wordpress backup size. Resulting in taking more time in saving and restoring the backup.

As a best practice, you should only deactivate the plugin when you are doing for time being. However, if you are not planning to use it any soon or ever, then you should deactivate it and delete it. This will prevent a lot of “junk data” and reduce the backup size.

How to delete wordpress plugin(the proper way)

This is scenario one, where you have the access to the admin area. In this case, it is real quick and easy. Furthermore, this is one of the scenarios. The main scenario of how to delete wordpress plugin without the admin access is in the subsequent section.

So let’s begin.

Delete wordpress plugin from the admin area

Step 1

Log in to your admin area and navigate to the plugin menu from the left menu section. Alternatively, you can also go to “Installed plugins” page by hovering on the plugin menu. Once the page loads, all you have to do is click on “deactivate” link

Step 2

The last step is to delete the plugin you have just deactivated. This is to ensure that the plugin does not occupy space either in the backup or the database. To delete, simply click on the delete link. This will delete the plugin from your database.

Note: You can also bulk delete wordpress plugins by simply selecting all the plugins you want to delete (checkboxes) and click on the “Bulk Actions” drop down to bulk delete plugins.

Delete wordpress plugin from the FTP(File transfer protocol)

This is the second common way that you can use to delete wordpress plugin. FTP is a service that helps you connect to your server via your laptop/desktop. Once you connect FTP to wordpress, you can upload files manage your server without logging into your hosting dashboard.

Now to delete WordPress plugin via FTP, you’ve to follow the following steps:

Step 1

Login to your SFTP

Step 2

Navigate to /wp-content/plugins/ folder. Find and delete the folder from the list. That’s it. You saved yourself some space and helped your site load faster indirectly.

You can also delete wordpress plugins without FTP too. Now things get weird from here.

Delete wordpress plugin from the backend/database via Cpanel 

Remember I said that I accidentally downloaded a plugin that disabled my access to the admin area?

Yeah, the plugin was RefferalCandy. I was testing the plugin and failed to notice that it needs WooCommerce integration with wordpress to function right. I did not have the integration and hence lost the access. You might be facing or have faced such situations. For those who are facing this issue right now, here’s the fix:

Step 1

Connect to the hosting dashboard provided by your hosting provider. Mostly it’s Cpanel.

Step 2

Scroll down and find “File Manager” in the Files section. Click on the File Manager and you will be taken to the file management system of your server.

Step 3

Double click on “public_html” link in the table on the page. Make sure you are on the home directory (you’ll find public_html only in the home directory), if not click on home directory of your server. It’s generally named after your website name.

Step 4

If you’ve hosted just one domain on your server, then you can directly find the wp_content folder in the table under public_html directory.

In case you have hosted multiple domains, locate that domain name (you’ll see a folder named after your domain name) and double click on it to open it. You’ll find the wp_content folder there.delete wordpress plugin from cpanel

Step 5

Once you are into the wp_content folder, look for Plugins folder. Double-click to open the folder.

Step 6

Find the plugin folder accidentally installed, and single-click on the folder and then click delete link above the table in the menu ribbon.

Note: Refresh the table once, to ensure a successful deletion.

Removing unused shortcodes

There are a lot of plugins that use shortcodes. You need to delete the shortcodes separately. Shortcodes are generally used to add things to your posts or pages just like the way you add the HTML code. Once you deactivate or uninstall wordpress plugins that run on shortcode concept, the shortcode will be visible on your website and make your page look ugly. Finding each and every page where you’ve added the shortcode is practically inhuman and time-consuming. But don’t worry, there’s a shortcut;

To disable the shortcodes, add the following code in your functions.php file.

add_shortcode( 'pluginshortcode', '__return_false');

This code simply make the shortcode invisible to the end users. All you have to do is, note down the shortcodes you’ve used in such wordpress plugins and replace each of them with ‘pluginshortcode' in the functions.php file. Remember, to have all shortcode mentioned in the functions.php file else, the codes will be visible on your web pages.

Note: If you ever decide to use that plugin again, remember to remove the above-mentioned code. Else the shortcodes from the plugin will not work, as the code above is making it invisible and hence pointless.

The above-mentioned methods are the most common ways to delete wordpress plugin. However, this is not all you should be doing. As I have mentioned earlier, most of the plugins leave behind residuals just like the app on an Android device or iOS device.

To remove this, there’s a better approach; That’s to clean the database table manually.

How to clean the wordpress database manually (delete wordpress plugin tables left behind)

This option is when you’ve already got rid of wordpress plugins and what to remove the leftovers. Alternatively, you may need to do a casual cleanup of your wordpress database (which is a good practice)

The reason for doing these manual steps is the fact that many wordpress plugins create tables to store its data in your database. This further occupies space, which may prove costly for on-the-go plan users or those who have limited space on the server for their website.

There are two ways by which you can clean wordpress database manually.

  1. Via phpMyAdmin
  2. Advanced Database Cleaner

Let me explain each of it in detail.

Note: Before you begin, make sure you take a back up of your wordpress data. In case you go wrong somewhere, you can restore the data. If you are Kinsta user, creating a secure backup is one-click away.

Clean wordpress database manually via phpMyAdmin

I personally prefer this method over using a plugin, as it more or less means the same- A plugin to remove another plugin. But if you are a person who wants to stay away from these lengthy steps, you can directly skip to the plugin step (its easy & straight). Furthermore, this step involves a basic knowledge of SQL & Database, if that’s not your cup of tea, there’s a plugin for this.

Step 1

Login to your hosting dashboard (CPanel) and find phpMyAdmin under databases section.
