Have you ever tried adding a new post or updating a plugin on your WordPress site only to receive the error “Database Error: Disk Full”? That means your server is running low on storage, preventing the database from saving new data.
When this happens, your site might misbehave by failing to load plugins, store content, or function properly. In this guide, I’ll explain what’s causing the error and how you can quickly get your site back on track.

What Causes the WordPress “Database Error: Disk Full”?
This error appears because your server lacks enough space, which stops MySQL from writing data to the WordPress database. Some common reasons include:
- Limited Hosting Plan Storage: Your hosting plan may not provide enough space as your site grows.
- Unnecessary Files in the Database: Old post revisions, expired transients, and spam comments can bloat your database.
- Too Many Plugins and Themes: Even inactive plugins and themes consume storage unnecessarily.
- Large Backup Files Stored on Server: Backups saved locally can quickly fill your disk space.
- Cache and Log Files Overload: Temporary files from caching plugins or server logs can pile up over time.
3 Easy Ways to Fix WordPress Database Error: Disk Full
- Upgrade Your Hosting Plan
- Remove Unnecessary Files in the Database
- Delete WordPress Plugins and Themes
1. Upgrade Your Hosting Plan
A common reason for the “WordPress database error disk full” is that your hosting plan doesn’t have enough storage. Hosting providers allocate a set amount of space, which is used up by your database (such as posts and comments) and other files, such as media, plugins, and themes.
If you’re on a basic plan with limited storage, you might quickly run out of space as your site grows.
The easiest way to solve this is to upgrade to a hosting plan with more storage or switch to a provider with better capacity and performance options.
2. Remove Unnecessary Files in the database
A cluttered WordPress database can fill up with post revisions, expired transients, and other unnecessary data, contributing to the “Database Error: Disk Full” issue. Below are two ways to clean your database:
Use a Plugin:
Go to Plugins > Add New in your WordPress dashboard.
Search for “WP-Optimize” or “Advanced Database Cleaner” and click Install and Activate.
Go to the plugin’s settings page. Select the options to remove post revisions, trashed posts, spam comments, and expired transients. Finally, click Run Optimization to clean the database.
Use Manual Way:
Open your hosting provider’s dashboard (such as cPanel or Plesk) and navigate to the Databases section. Click on phpMyAdmin to access your database.
In phpMyAdmin, click on the WordPress database (often named something like wp_yoursite).
Use the Export feature in phpMyAdmin to back up your database before making any changes.
After Exporting your database, phpMyAdmin will display a list of all the tables stored on your website. You can click on any table to view its contents.
A list of data in that table will appear on your screen. From there, click the ‘Delete’ link next to any files you consider unnecessary or taking up too much space in your database.
Either method can quickly free up space in your database, reducing the chances of running into the “Disk Full” error again. Regularly optimizing your database ensures your WordPress site stays fast and healthy.
3. Delete WordPress Plugins and Themes
Unused plugins and themes take up space and can lead to the “Database Error: Disk Full” issue. Even inactive ones use storage and leave clutter in your database. Deleting them frees up space and keeps your site running smoothly. Here’s how to do it.
Log in to your WordPress dashboard and navigate to Plugins > Installed Plugins.
Click the ‘Delete’ link next to the plugins you want to remove.
Next, go to Appearance > Themes to delete any themes you’re not currently using.
You can delete WordPress themes by clicking the ‘Theme Details’ button.
A prompt will appear where you need to click the ‘Delete’ link.
After deleting plugins and themes, cleaning up leftover data in your database is a good idea.
Conclusion
Fixing the “WordPress Database Error: Disk Full” is about managing storage. Start by removing unnecessary files from your database and deleting any plugins or themes you don’t use.
If your site keeps growing and needs more space, upgrading your hosting plan is a good idea. These simple steps will help eliminate errors and keep your site running smoothly.
