Ever had the “WordPress Database Error Disk Full” error? If you have and you’re here to learn how to fix it, you’re at the right place. In this article, you’ll learn the reasons why this happens, as well as how to fix the “WordPress Database Error Disk Full” error.
What Would Cause The “WordPress Database Error Disk Full” Error?
The “WordPress Database Error Disk Full” error usually indicates that the disk space on the server where your WordPress site is hosted is full. Here are nine potential reasons why this error might occur:
Large Database Files
Backup Files
Unoptimized Database
Large Media Files
Log Files
Cache Files
Temporary Files
Unused Themes and Plugins
Server Configuration Issues
Large Database Files
Over time, your WordPress database can grow large due to accumulated data, revisions, or logs, potentially filling up disk space.
Backup Files
If your site generates backups, for example, daily backups or multiple versions, these can consume significant disk space. If backups are stored on the same server, they could fill up the disk.
Unoptimized Database
A database that hasn’t been optimized or cleaned up can accumulate overhead, temporary tables, or orphaned data, consuming more space than necessary.
Large Media Files
If you upload large media files (images, videos, etc.) frequently, these files can quickly use up available disk space.
Log Files
Error logs or other server logs can grow significantly, especially if there are recurring issues or a lot of traffic. These logs might be stored on the same disk as your WordPress installation.
Cache Files
Some caching plugins or systems store large amounts of data. If not managed properly, cache files can fill up your disk space.
Temporary Files
WordPress and its plugins may create temporary files that can accumulate if not cleaned up properly.
Unused Themes and Plugins
Having multiple themes and plugins, especially those that are not regularly updated or used, can contribute to increased disk usage.
Server Configuration Issues
Sometimes, server misconfigurations or limits on disk space allocation can lead to issues where your disk appears full even if it shouldn't be.
To resolve the issue, you might need to delete unnecessary files, optimize your database, manage your backups more effectively, or contact your web hosting provider to increase your disk space.

Step 1. Check Disk Space Usage
Here’s how to check disk space usage:
Log in to your hosting account
Analyze disk space
Document the findings
Log in to your hosting account
Use your hosting provider’s control panel (example: cPanel or Plesk) or FTP/SFTP (example: Filezilla or WinSCP) to access your server. Look for disk usage statistics, often found in the file manager or through a specific disk usage tool provided by your host.
Analyze disk space
Identify which directories or files are consuming the most space. Pay particular attention to large directories like wp-content/uploads or any backup directories.
Document the findings
Take note of the largest files and directories, as this will help you prioritize which files to clean up or manage.
Step 2. Clean Up Unnecessary Files
Here’s some steps to cleaning up unnecessary files:
Remove old backups
Delete unused themes and plugins
Clear temporary files
Remove old backups
If you have multiple backup files, delete older versions that you no longer need. Make sure to keep at least one recent backup in case of emergencies.
Delete unused themes and plugins
Access the WordPress admin dashboard, go to the “Themes” and “Plugins” sections, and delete any themes or plugins that are not being used.
Clear temporary files
Locate any temporary files created by WordPress or its plugins. Often, these are stored in the wp-content folder and can be safely removed if not needed.
Step 3. Optimize Your Database
Install a database optimization plugin
Run optimization tasks
Manually optimize (if needed)
Install a database optimization plugin
A plugin like WP-Optimize can help clean up your database by removing unnecessary data such as post revisions, spam comments, and transient options.
Run optimization tasks
Follow the plugin’s instructions to optimize tables and clean up overhead. Ensure you have a recent backup before performing any database operations.
Manually optimize (if needed)
You can also manually optimize your database using phpMyAdmin. Go to phpMyAdmin, select your database, check all tables, and choose Optimize Table from the dropdown menu. If you use this option, rather than using a plugin like WP-Optimize, make sure to backup your site’s database.
Step 4. Manage Media Files
Delete unused media files
Compress large images
Consider external storage
Delete unused media files
Use a media library management plugin to identify and remove unused or orphaned media files from your WordPress installation.
Compress large images
Optimize existing images using plugins like Smush or ShortPixel. This reduces file sizes without compromising quality, freeing up disk space.
Consider external storage
For large files or extensive media libraries, consider using an external service like Amazon S3 to offload media storage from your server.
Step 5. Clear Cache Files
In some cases, you might need to clear your file cache. Here’s some tips to do that:
Clear cache via plugins
Delete cache manually
Reconfigure caching settings
Clear cache via plugins
If you’re using a caching plugin (example: WP Rocket, WP Super Cache), navigate to the plugin’s settings and clear all cached files. This can free up significant space if the cache is large.
Delete cache manually
If you don’t have a caching plugin, manually delete cache files stored in directories like wp-content/cache or similar.
Reconfigure caching settings
Review your caching settings to ensure they are not generating excessive cache files or storing them unnecessarily.
Step 6. Review and Manage Log Files
Reviewing your log files, like your error logs, is important. Here’s some steps to reviewing and managing log files:
Access log files
Rotates or delete logs
Address underlying issues
Access log files
Check the server’s log files, which might be located in directories like /var/log/
or specific folders in your WordPress installation.
Rotate or delete logs
If logs are consuming too much space, configure log rotation to archive old logs or delete logs that are no longer needed.
Address underlying issues
Ensure that any recurring issues generating large logs are resolved to prevent future disk space problems.
Step 7. Increase Disk Space
In some cases, you might need to get more disk space. Here are some steps to increasing disk space for your web site:
Contact your hosting provider
Upgrade your hosting plan
Verify the increase
Contact your hosting provider
If you have cleaned up your site but still face space issues, reach out to your hosting provider to discuss increasing your disk space allocation.
Upgrade your hosting plan
If you are on a shared hosting plan, consider upgrading to a higher-tier plan or a VPS if your site’s requirements have outgrown the current plan.
Verify the increase
After requesting more disk space, verify that the additional space has been allocated and is available for use.
Step 8. Monitor Disk Usage Regularly
As your site grows, it’s important to monitor disk usage. Here’s some tips towards monitoring your website’s disk space regularly:
Set up alerts
Schedule regular maintenance
Review usage periodically
Set up alerts
Use your hosting provider’s tools or plugins to set up disk space alerts to notify you when your disk usage approaches critical levels.
Schedule regular maintenance
Regularly check and clean up your site’s files and database to prevent space issues from recurring.
Review usage periodically
Make it a habit to review disk usage statistics and perform cleanups as needed to maintain optimal performance and space availability.
