How to Fix the “Destination Directory for File Streaming Does Not Exist or Is Not Writable” Error in WordPress

Keeping your WordPress website updated is vital for security, performance, and overall stability. However, during updates, you might encounter errors like:

“An error occurred while updating [plugin name]: Download failed. Destination directory for file streaming does not exist or is not writable.”

This error can disrupt your website’s operation, making updates impossible. Fortunately, this issue is both common and fixable. In this guide, we’ll cover the causes and provide step-by-step solutions. If you’re looking for a trusted partner to manage these issues and ensure smooth updates, RubyWeb is here to help with expert WordPress maintenance services.

Why Does This Error Occur?

This error appears when WordPress cannot download and save files while updating plugins or themes. Common reasons include:

1. Missing or unwritable directories (like wp-content/upgrade).
2. Incorrect file and folder permissions.
3. Server-level restrictions or insufficient disk space.
4. Conflicts with caching tools like Redis Object Cache or WP Rocket.

For website owners, understanding these causes is crucial. However, resolving them can be complex without technical expertise.

Step-by-Step Solutions to Fix the Error

1. Verify the wp-content/upgrade Folder

WordPress uses the upgrade folder to temporarily store files during updates.

Steps to Fix:

1. Log in to cPanel and open the File Manager.
2. Go to public_html/wp-content/.
3. Check for the upgrade folder.
   • If it’s missing, create a folder named upgrade.
4. Set its permissions to 755.

2. Add a Custom Temporary Directory

If WordPress cannot locate a suitable temporary directory, you can define one manually.

Steps:

1. In wp-content/, create a folder named tmp.
2. Open wp-config.php in your root directory.
3. Add this code near the top:phpCopy codedefine('WP_TEMP_DIR', ABSPATH . 'wp-content/tmp/');
4. Save the file and try updating again.

This fix ensures WordPress has a reliable temporary location for updates.

3. Check and Correct Folder Permissions

Incorrect file and folder permissions often block updates. The correct settings are:

• Folders: 755
• Files: 644

Steps:

1. Go to the File Manager in cPanel.
2. Right-click the wp-content, upgrade, and tmp folders.
3. Set their permissions to 755.

4. Clear WordPress and Server Cache

Caching tools like WP Rocket and Redis Object Cache can sometimes interfere with updates.

• Flush Redis Cache: Go to Tools > Redis > Flush Cache.
• Clear WP Rocket Cache: Navigate to WP Rocket > Dashboard > Clear Cache.

Clearing caches ensures WordPress reads the latest directory paths.

5. Verify PHP Settings and Disk Space

Server settings and storage limitations can also cause update failures.

• Increase PHP limits:
  • upload_max_filesize = 64M
  • post_max_size = 64M
  • memory_limit = 256M
  • max_execution_time = 300
• Check for available disk space in cPanel > Disk Usage.

6. Seek Professional Assistance

If these steps seem complex or time-consuming, it’s always best to work with a trusted WordPress maintenance partner. Errors like these can affect your site’s performance and leave it vulnerable to risks.
