Fix WordPress Plugin Update Failed (Complete Guide)

Seeing the “Plugin update failed” error in WordPress can be frustrating, especially when you rely on plugins for security, performance, or functionality.
This issue can break your site, leave plugins outdated, and even expose you to security risks.
The good news? This error is completely fixable.
In this guide, you’ll learn why WordPress plugin updates fail and how to fix them step-by-step, even if you're not a developer.
Why WordPress Plugin Updates Fail
Before fixing the issue, it's important to understand the root causes.
Common Reasons:
- File permission issues
- Insufficient PHP memory
- Timeout errors
- Broken internet connection
- Plugin conflicts
- Server restrictions
- Disk space full
Step 1: Check the Exact Error Message
WordPress may show:
- “Update failed: Download failed”
- “Could not create directory”
- “Installation failed”
Each error gives a clue about the problem.
Step 2: Check File Permissions
Incorrect permissions are one of the most common causes.
Recommended Permissions:
- Folders → 755
- Files → 644
Fix Permissions via SSH:
chmod -R 755 wp-content/plugins
chmod -R 644 wp-content/plugins/*
Step 3: Increase PHP Memory Limit
Low memory can cause updates to fail.
Edit wp-config.php:
define('WP_MEMORY_LIMIT', '256M');
Step 4: Enable Debug Mode
To identify the exact issue:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
Check logs inside:
/wp-content/debug.log
Step 5: Check Disk Space
If your server is full, updates will fail.
df -h
Free up space if needed.
Step 6: Fix FTP Credentials Issue
WordPress may ask for FTP details.
Solution:
Add this in wp-config.php:
define('FS_METHOD', 'direct');
Step 7: Disable All Plugins Temporarily
Sometimes plugins conflict.
- Go to Plugins → Deactivate all
- Try updating again
Step 8: Manually Update Plugin
If auto update fails, do it manually.
Steps:
- Download plugin from WordPress.org
- Extract ZIP
- Upload via FTP to:
/wp-content/plugins/
- Replace old folder
Step 9: Check Server Timeout
Increase execution time:
set_time_limit(300);
Step 10: Fix Folder Ownership
chown -R www-data:www-data /var/www/html
Step 11: Check Hosting Restrictions
Cheap hosting often blocks updates.

Step 12: Check Internet Connectivity
Server must access WordPress.org.
Test:
ping wordpress.org
