Fix: “WordPress Database Error Disk Full” Error

WordPress errors are often disruptive to your website maintenance. Simple tasks take much longer than they usually take. 

Perhaps you  were trying to install a plugin and not able to do it? Maybe you were trying to publish a post on your WordPress site, and were unsuccessful. Instead, you are faced with an error saying the disk storage is full? 

A full disk error happens when your hosting storage limit is reached. WordPress can’t save new data, like a plugin or a post, because there’s no space left. Thankfully, there are solutions to free up space and get your site running smoothly again. We’ve put together a list of steps you can take in this article. 

TL;DR: To fix a full disk error, optimize your database tables and delete unnecessary or unused items – plugins or themes. However, backup your site with MalCare first to prevent data loss in case you accidentally delete something you actually need.

What is the “WordPress Database Error Disk Full” error?

The “WordPress Database Error Disk Full” error occurs when your server’s disk space reaches its limit. This error stops WordPress from saving new data. Disk space in WordPress is used by database tables, which include posts, pages, and comments. It also stores user data, profiles, settings, and configurations. Your plugins and themes add to this space, as do revisions and metadata from your content. When all this space is maxed out, you face the disk full error, which can disrupt your website’s functionality.

In our experience, we’re constantly installing plugins to test for our articles. For example, we tested all the top security plugins for a listicle. We had also tested some page builders where we created full fledged pages. (You’d be surprised at how heavy they can be) After months of not doing anything about it, we were met with this error ourselves! It was a wake-up call that we had to go back and uninstall plugins we weren’t using.  

It’s a simple fix but it can be frustrating. Let’s say you’re ready to capture a sunset with your camera. Just as you press the button, an error pops up: “Storage Full.” The moment passes while you scramble to clear space. It’s frustrating, right? Similarly, on your WordPress site, if you don’t regularly check and clear storage, you might run into a disk full error at the worst time. Everyday tasks like publishing posts or updating content can come to a halt. This disruption is not just a technical hiccup; it can affect your site’s visitors and your workflow.

How to fix the WordPress Database Error Disk Full” error?

The WordPress databasecan max out on storage for several reasons. Perhaps your server storage limit is smaller than your website demands, or maybe you’ve accumulated too many large files or media uploads over time. Sometimes, it’s the excessive post revisions or unoptimized database size that eat up space. Backups can also add up, further cramping your storage. Additionally, data bloat from plugins or themes and temporary files not being cleared can contribute to the problem. Finally, if your hosting plan doesn’t match your site’s growth, you could find yourself facing storage issues. To fix this error, it’s important to identify and address these potential causes with proactive measures.

Pro tip: If you have cPanel, you can easily find your file usage by looking for files and database usage in the sidebar. Another option is to use your web host’s control panel, as many hosting providers offer tools similar to cPanel that can display storage use. Even database managers like Webmin show you how much disk space has been occupied. 

Increase hosting resources

As your website grows and accumulates more content, you might reach the limits of your current hosting plan, causing the “WordPress Database Error Disk Full” message to appear. This happens when the plan’s storage is no longer sufficient to handle your site’s media files, plugins, and updates. A once-adequate plan can become a constraint, affecting your site’s performance and functionality. If you have a good hosting provider, they will be able to modufy your plans to increase your resource allocation.

How to fix it?

Contact your hosting provider.

Discuss your current and anticipated storage needs. Explore plans with more space and resources. Select and upgrade to the recommended plan. Ensure the new plan supports future site growth.

Clear database space

Over time, your WordPress database can become cluttered with unnecessary data. This clutter can come from accumulated revisions, auto-draft posts, old plugins, and other transient data. If left unchecked, it can slow down your site and cause frustrating storage errors, impacting the overall performance and speed of your website.

How to fix it?

Use plugins like WP-Optimize to optimize your database.

• Install and activate the plugin on your WordPress site.
• Click the WP-Optimize icon in the sidebar of your dashboard.
• Select the specific optimizations you want to perform, such as removing pingbacks, deleting revisions, clearing auto-draft and trash posts and executing the optimization process to clean and free up space in your database.

Expert advice: You can also do this manually. You can select database tables and just delete them. But, this is time consuming, prone to the risk of data loss and requires the technical know-how to understand which tables can be deleted. 

Delete unused WordPress themes and plugins

Each time you install a new theme or plugin, you are using up more of your server’s valuable storage space. If you use nulled plugins, you may also be instaling badly written plugins that add bloat. Unused or inactive themes and plugins can accumulate over time, contributing to the “WordPress Database Error Disk Full” problem. By keeping unnecessary ones, you not only occupy space but also potentially slow down your website’s performance.

How to fix it?

Identify and delete themes and plugins you no longer use or need.

• Navigate to your WordPress dashboard.
• Go to Plugins > Installed Plugins.
• Select the plugins you wish to delete and click on Delete to free up space.
• Repeat the process for themes by going to Appearance > Themes and removing unused ones.

Pro-tip: Find plugins that offer multiple functions to reduce the number of plugins required. For example, MalCare has security, backups and performance optimization features that you can implement with their paid pans. You don’t need separate plugins for each of those functions. 

Remove large log files

WordPress log files, especially when they grow large, can consume significant amounts of storage space on your server. Over time, these files can contribute to the “WordPress Database Error Disk Full” issue, as unnecessary or old logs continue to pile up. Regularly reviewing and managing your log files can help free up valuable space and improve your website’s performance.

How to fix it? 

Find and remove large log files

• Access your server using cPanel.
• Navigate to File Manager.
• Locate the Logs directory.

Note: The logs directory is typically located in the root directory of your hosting account. However, its exact location can vary based on your hosting provider and server configuration.

• Review the files and delete unnecessary or outdated log files to reclaim space on your server.

If you’ve tried various solutions and the “WordPress Database Error Disk Full” issue persists, it might be time to reach out to your hosting support team. They have the access and tools needed to troubleshoot. 

Prevent the“WordPress Database Error Disk Full” error

Troubleshooting the “WordPress Database Error Disk Full” problem can be a time-consuming and frustrating ordeal. It often involves sifting through files, deleting unnecessary data, and sometimes making repetitive adjustments. This is why putting effort into preventing this error is important.

Regularly monitor disk space

Keeping an eye on your disk space usage is essential. Access your cPanel and use the search function for disk usage to review how storage is being utilized. Sort the items by disk usage to quickly identify any large files or directories that might be consuming excessive space.

You can also use tools like WP-Optimize to review how your server usage is doing. Regular monitoring allows you to catch and address potential issues before they escalate.

Optimize database periodically

Your database can become cluttered with redundant data over time. Regularly optimizing it can significantly reduce unused data and improve your site’s performance. Consider using plugins like WP-Optimize to automate this process. This routine maintenance ensures that your database remains efficient and free of unnecessary bloat.

Limit post revisions

WordPress saves multiple revisions of your posts, which can rapidly consume database space. By limiting the number of WordPress revisions saved, you can conserve valuable storage. Adjust the post revision settings to suit your needs. [Link to article]

Clean up media library frequently

Unused or redundant media files can quickly occupy significant space on your server. Schedule regular reviews of your media library to delete any files that are no longer needed. This practice not only frees up space but also helps keep your library organized.

Take offsite backups

Implement an automated backup solution that uses offsite server functionality, like MalCare. This ensures that backups don’t take up space on your main server, while still safeguarding your data. Regular offsite backups provide peace of mind and secure your content against data loss.

Implement cache management practices

Effective cache management can reduce server load and improve your site’s speed. By using caching plugins and strategies, you ensure efficient use of server resources without unnecessary space consumption.

Remove unused themes and plugins

Regularly audit your themes and plugins. Deactivate and delete any that are not in use to reclaim space and optimize site performance. This practice prevents unnecessary data from accumulating and keeps your site lean.

Set alerts for low disk space

Configure disk space alerts to notify you when your server’s storage is running low. This foresight allows you to take immediate action, preventing potential disruptions due to space constraints.

Upgrade hosting plan as needed

Stay responsive to your site’s growth by upgrading your hosting plan to meet increasing storage needs. As your website expands, consider plans with higher storage capacity and resources. Discuss your site’s growth with your hosting provider to find a plan that aligns with your future demands.

Final Thoughts

Encountering the “WordPress Database Error Disk Full” issue can indeed be frustrating, but thankfully, there is an easy fix. Just take the time to carefully pick and choose files and database tables that you don’t need for your site functionality. 

However, before making any changes, we strongly recommend taking a full backup of your site using a solution that offers offsite server storage, such as BlogVault. This precaution ensures that your data is safe, allowing you to make necessary adjustments without the risk of losing important information.
