Introduction to Disabling WordPress Plugins via phpMyAdmin on Linux

If you’re managing a WordPress site on a Linux server, mastering phpMyAdmin for plugin management can be a crucial skill. This guide will walk you through the steps of how to disable WordPress plugins directly from phpMyAdmin, an essential skill for every DevOps and system administrator dealing with website maintenance and troubleshooting.

Why Disable Plugins from phpMyAdmin?

Disabling plugins from the WordPress admin dashboard is straightforward, but what if you can’t access your dashboard? Perhaps your site is down, or a plugin is causing a conflict. In such cases, phpMyAdmin is a powerful tool in your arsenal, allowing you to use phpMyAdmin for plugin management without needing to access the WordPress dashboard.

Accessing phpMyAdmin

First, ensure you have access to phpMyAdmin on your Linux server. This tool is typically provided by your hosting provider or can be installed directly on your server.

Identifying the WordPress Database

Once you’re in phpMyAdmin, the next step is to locate your WordPress database. It is usually named something like wp_yoursite but can vary based on your installation or host settings. The database name can be verified by checking the wp-config.php file in your websites files. View the file and look for

define( 'DB_NAME', 'my_database_name' );

Step-by-Step Guide to Disabling Plugins

Follow these detailed instructions to disable a WordPress plugin directly through phpMyAdmin:

Step 1: Back Up Your Database

Before making any changes, it’s wise to back up your database. Here’s how you can export your database in phpMyAdmin:


1. Click on your WordPress database.
2. Go to the "Export" tab.
3. Choose the "Quick" export method and the "SQL" format.
4. Press "Go" to download the SQL backup file.

Step 2: Edit the Active Plugins

Navigate to the wp_options table within your WordPress database. Look for the option_name column and find the entry named active_plugins.


SELECT * FROM wp_options WHERE option_name = 'active_plugins';

This row contains the list of all active plugins, stored in a serialized array format.

Step 3: Disable Plugins

To disable WordPress plugins, you need to modify the active_plugins entry in your database. Be cautious when editing serialized data—improper modifications can cause issues. Use an online serialization tool to unserialize and reserialize the data safely.

To Disable a Specific Plugin:

  1. Access the active_plugins option in the wp_options table via your database management tool (e.g., phpMyAdmin).
  2. Copy the serialized array from the option_value field.
  3. Use an online unserialization tool to convert the serialized array into a readable format.
  4. Locate and remove the entry corresponding to the plugin you want to disable.
  5. Serialize the updated array using the same tool.
  6. Replace the serialized array back into the option_value field and save the changes.

To Disable All Plugins:

  1. Navigate to the wp_options table in your database.
  2. Locate the active_plugins option.
  3. Replace the option_value field with an empty serialized array:
    a:0:{}
  4. Save the changes to disable all plugins at once.

Pro Tip: If you’re uncertain about the serialized data or encounter issues, you can rename the plugins folder in wp-content to something like plugins_disabled. This will deactivate all plugins without modifying the database and can be easily reversed by restoring the folder name.
