Primary Causes of Upload Failures in WordPress
When you see the “Upload: Failed to Write File to Disk” error in WordPress, it’s important to know why. The main reasons are WordPress file permissions, not enough server disk space, and temporary folder problems.
File permissions are key. They decide who can do what with files and folders. If they’re wrong, like being set at 644 for files and 755 for folders, WordPress can’t write files. Making sure the uploads folder has the right permissions is a big first step.
Not having enough server disk space is another big problem. When the WordPress Media Library gets too big, the server runs out of room. It’s important to watch and manage your server’s disk space to keep your site running well.
- Problems with the temporary folders used during uploads can also cause the “Failed to Write File to Disk” error.
- Server settings that limit file size or have security issues can also stop files from being written.
- Corrupted WordPress files, plugin or theme problems, and server limits can all cause upload failures.
Knowing these main reasons is the first step to fixing the “Upload: Failed to Write File to Disk” error on your WordPress site.

Initial Diagnostics Steps
To start fixing the error, find out what’s causing it. First, check your file permissions with the WordPress Site Health tool. Go to “Tools” > “Site Health” in your WordPress dashboard.

Adjusting Permissions Through Web Hosting Control Panel
When you get the “Upload: Failed to Write File to Disk” error in WordPress, changing file permissions helps. You can do this through your web hosting control panel. This lets you set the right permissions for the WordPress uploads folder. This way, your site can write and save media files without trouble.
Step-by-Step Permission Configuration
To change permissions through your web hosting control panel, just follow these steps:
- Go to your web hosting control panel. It’s usually in your web host’s dashboard.
- Find the File Manager or File Explorer in the control panel.
- Look for the public_html directory. It’s the main folder for your WordPress site.
- In the public_html folder, find the wp-content directory. Then go to the uploads folder.
- Right-click on the uploads folder. Choose “Permissions” or “Properties”.
- Make the uploads folder’s permissions 755. This lets the web server write files there.
Verifying Changes in WordPress Dashboard
After changing permissions, check your WordPress dashboard. Here’s how:
- Log in to your WordPress admin dashboard.
- Go to the media upload section. You can do this by adding a new media item or trying to upload a file.

Managing WordPress Temporary Folder Issues
One common cause of the “Upload: Failed to Write File to Disk” error in WordPress is the temporary folder for file uploads. If this folder is full or can’t be reached, you can’t upload files. This stops you from adding new content or updating plugins and themes.
The WordPress temporary folder is hidden and hard to get to with FTP or hosting control panels. To fix issues with this folder, you need to ask your hosting provider for help. They can clear out the folder and make sure it has enough space for your uploads.
- Contact your WordPress hosting provider for support in managing the temporary folder
- Request their guidance in accessing and clearing the temporary files that may be causing the “Failed to Write File to Disk” error
- Follow any instructions provided by your hosting provider to optimize the WordPress temporary folder and prevent future upload failures
By working with your hosting provider, you can quickly find and fix problems with the WordPress temporary folder. This will get your website’s content management back on track.
Resolving Server Disk Space Limitations
Disk space issues can cause the “Upload: Failed to Write File to Disk” error in WordPress. If your server’s disk space is low, WordPress can’t save new files or content. We need to check your disk usage and find ways to free up space or upgrade your hosting.
Checking Current Disk Usage
First, we need to see how much disk space you’re using. You can find this info in your hosting account dashboard or control panel. For example, Kinsta users can check their disk usage in the MyKinsta dashboard under “Resource Usage”.
If you’re running low on disk space, it’s time to act. You can delete unused files, optimize your WordPress database, or upgrade your hosting plan. These steps can help solve the problem.
Options for Disk Space Management
- Delete Unused Files: Find and remove files, images, or media you no longer need. Cleaning up your site regularly can save disk space.
- Optimize Database: Your WordPress database can grow too big. Use a plugin like WP-Optimize or try manual methods to make it smaller.
- Upgrade Hosting Plan: If you need more space, consider upgrading to a WordPress hosting plan with more server disk space. This can give you the extra room you need.
By managing your disk usage and server disk space, you can fix the “Upload: Failed to Write File to Disk” error in WordPress.
Advanced Troubleshooting Through SSH Access
As a WordPress VPS user, you have SSH (Secure Shell) access. This can change the game when you face the “Upload: Failed to Write File to Disk” error.
SSH lets you use command line file permissions. You can change your WordPress files and folders with the chmod command. For example, you can make a directory’s permissions 755 with chmod 755 wp-content. Don’t forget to add -R for all subdirectories.
But, be careful with command line tools. A wrong move can cause big problems. Make sure you know what you’re doing before you do it.
SSH also helps with WordPress VPS hosting problems. It lets you look deeper into the server’s files. This is great for checking disk space or file permissions.
Even if you fix the error with your hosting control panel or FTP, SSH is useful for more complex issues. It’s a powerful tool for advanced users.
Preventing Future Upload Errors
To keep your WordPress site running smoothly, it’s key to do regular maintenance. This means watching your disk space, updating your site, and checking file permissions often.
Best Practices for File Management
Checking your disk space regularly helps spot storage issues early. Use your web hosting control panel to see how much space you’re using. Then, clean up unused files or optimize your media library.
It’s also important to keep your WordPress, themes, and plugins updated. Old software can cause problems and make your site vulnerable. Make sure everything is current.
Regular Maintenance Tips
Think about using a WordPress maintenance plugin like iThemes Security or Jetpack. These tools can help with file management, disk space monitoring, and alert you to issues. This way, you can fix problems before they get worse.
Also, check your WordPress file permissions often. Make sure your wp-content/uploads directory and its files have the right permissions. You can do this through your hosting control panel or an FTP client.
