As a WordPress user, one of the most frustrating issues you can encounter is the WordPress Updating Failed error. Whether you’re trying to update your WordPress core, plugins, or themes, encountering an error can disrupt your workflow and leave your website vulnerable if updates aren’t applied.
While this error can seem intimidating, it’s usually something that can be resolved without too much hassle. In this comprehensive guide, we’ll walk you through five simple steps to fix the WordPress Updating Failed error, all while optimizing your WordPress site for better performance and security.
What Does WordPress Updating Failed Mean?
Before jumping into the fixes, it’s important to understand the core issue. The “WordPress Updating Failed” error typically happens when WordPress is unable to finish the update process.
This can apply to updates for WordPress core, plugins, or themes. The failure may be caused by issues such as server timeouts, memory limitations, conflicting plugins, or even file permission problems.
Understanding the specific cause is crucial for applying the right solution. Common reasons for encountering the WordPress Updating Failed error include:
- Server timeouts or network issues during the update process.
- Insufficient PHP memory limit, causing the update to fail.
- Plugin or theme conflicts, where one plugin or theme interferes with the update.
- Incorrect file permissions, preventing WordPress from making necessary changes.
- Outdated versions of WordPress or other components.
Let’s dive into the five steps that will help you resolve this issue.
Step 1: Check for Server or Network Issues
1.1 Why Server Issues Can Cause the Error
Sometimes, the problem isn’t with your WordPress site itself but with your web hosting environment. WordPress relies on server resources like processing power and network bandwidth to complete updates.
If your server is slow or facing downtime, it can prevent the update process from completing, leading to the WordPress Updating Failed error.
A slow server response can be caused by several factors, such as:
- High server load due to other users on shared hosting.
- Temporary server outages or issues on your hosting provider’s end.
- DNS resolution problems, which can affect communication between WordPress and the update servers.
1.2 How to Fix Server or Network Issues
- Test Server Performance: Use tools like Pingdom or GTMetrix to check if your website is experiencing any downtime or performance issues. These tools can give you a snapshot of your server’s health and help you identify if the problem is with your hosting environment.
- Ping Your Server: You can run a ping test from your computer to your server to check for any lag or connection issues. If the ping test shows high latency or no response, it may indicate a server problem.
- Contact Your Hosting Provider: If your tests reveal issues on the server side, contact your hosting provider. They may be experiencing downtime, server overload, or other problems that affect your WordPress updates. If you’re on shared hosting, upgrading to a VPS or dedicated hosting plan might be a solution to avoid this issue in the future.
- Check DNS Settings: Incorrect DNS settings can prevent WordPress from reaching its servers for updates. If you’re not sure how to check or adjust DNS settings, reach out to your hosting provider or use DNS services like Google DNS or Cloudflare DNS.
Step 2: Increase PHP Memory Limit
2.1 The Role of PHP Memory in WordPress Updates
One of the most common reasons for the WordPress Updating Failed error is insufficient PHP memory. WordPress relies on PHP to process updates, and if the allocated memory is insufficient, WordPress may fail to complete the update process. This is especially true for large plugin or theme updates or WordPress core updates.
When WordPress runs out of memory, you’ll typically see an error like this:
- Error Message: “Fatal error: Allowed memory size of X bytes exhausted.”
In such cases, increasing the PHP memory limit can often resolve the issue.
2.2 How to Increase PHP Memory Limit
Increase Memory via wp-config.php:
- Open your WordPress root directory via FTP or File Manager in your hosting control panel.
- Locate the wp-config.php file and open it for editing.
- Add the following line of code right before the
/* That's all, stop editing! Happy blogging. */comment:
define('WP_MEMORY_LIMIT', '256M');
This will increase the PHP memory limit to 256MB, which should be sufficient for most WordPress sites.Increase Memory via php.ini:
- If you have access to your server’s php.ini file, you can increase the PHP memory limit there as well:
memory_limit = 256M
This change applies to all PHP processes on your server, not just WordPress.
Contact Your Hosting Provider:
If you’re on a shared hosting plan or don’t have access to these files, contact your hosting provider to ask them to increase the PHP memory limit for your site.
After making these changes, try updating your WordPress site again to see if the issue is resolved.Step 3: Deactivate Plugins and Themes
3.1 How Plugins and Themes Can Cause the Error
Another frequent cause of the WordPress Updating Failed error is plugin or theme conflicts. WordPress plugins and themes often communicate with the WordPress core, and if a conflict arises, the update process may fail.
In particular, outdated or incompatible plugins can disrupt the update process. This is why it’s essential to keep plugins and themes updated regularly.
Additionally, sometimes two plugins or a plugin and a theme might conflict, causing the update to fail.
3.2 How to Fix Plugin and Theme Conflicts
- Deactivate All Plugins:
- Go to your WordPress Dashboard > Plugins > Installed Plugins.
- Select all plugins and choose Deactivate from the bulk actions dropdown.
- Once all plugins are deactivated, try updating WordPress again. If the update works, the issue is likely caused by one of the plugins.
- Reactivate Plugins One by One:
- Reactivate each plugin one at a time, checking after each activation to see if the error returns. If the error reappears after activating a specific plugin, you’ve identified the culprit.
- In some cases, outdated or incompatible plugins may need to be updated or replaced with alternatives.
- Switch to a Default Theme:
- Go to Appearance > Themes and activate a default WordPress theme like Twenty Twenty-Three.
- If the update succeeds after switching themes, it could be a theme conflict. In that case, try updating your theme or contact the theme developer for support.
- Check for Plugin or Theme Updates:
- Always ensure your plugins and themes are up to date. Developers regularly release updates that improve compatibility with WordPress updates.
Step 4: Check and Fix File Permissions
4.1 Why Incorrect File Permissions Can Prevent Updates
File permissions tell WordPress and the server what actions can be performed on certain files and directories. If the permissions are set incorrectly, WordPress may not be able to update files, causing the WordPress Updating Failed error.
For example:
- Incorrect permissions on critical files (like
wp-config.php) can prevent updates from completing. - Incorrect permissions on the wp-content folder can also block WordPress from writing to it during updates.
4.2 How to Fix File Permissions
- Check File Permissions via FTP:
- Use an FTP client like FileZilla to connect to your WordPress site.
- Right-click on your wp-content folder and select File Permissions.
- Set the permissions as follows:
- Files: 644
- Directories: 755
- Use the File Manager:
- Many hosting control panels offer a File Manager that allows you to set file permissions directly from the browser. Navigate to your WordPress root directory and adjust the file permissions for any problematic files or directories.
- Ensure Proper Ownership:
- Ensure that the files on your WordPress site are owned by the correct user. If the ownership is incorrect, WordPress may not be able to make changes to certain files, preventing updates. Check with your hosting provider if you’re unsure about the ownership of files.
Step 5: Update WordPress Manually
5.1 Why You Should Consider Manual Updates
If the automatic update process continues to fail, the next step is to perform a manual update. A manual update allows you to bypass any issues with the WordPress update process by directly uploading the new files to your server.
5.2 How to Update WordPress Manually
- Download the Latest Version of WordPress:
- Go to the official WordPress download page and download the latest stable version of WordPress.
- Extract and Upload Files:
- After downloading, extract the WordPress files on your computer.
- Using an FTP client, connect to your site and upload the new files. Be sure to exclude the wp-content folder and wp-config.php file to avoid overwriting your content and settings.
- Run the Upgrade Script:
- After uploading the files, go to
http://yourwebsite.com/wp-admin/upgrade.phpto run the upgrade script and complete the manual update.
- After uploading the files, go to
Additional Tips to Avoid the WordPress Updating Failed Error
- Backup Your Site Regularly: Use plugins like UpdraftPlus or BackupBuddy to create automatic backups of your website. Backups ensure that even if something goes wrong during an update, you can restore your site quickly.
- Monitor Update Logs: Many times, update logs will show detailed error messages that can help you diagnose the problem. You can check these logs via your hosting control panel or WordPress error logs.
- Choose a Reliable Hosting Provider: The performance and reliability of your web hosting can significantly affect your WordPress site’s ability to update smoothly. Consider upgrading to a more robust hosting plan if you frequently encounter update issues.
Conclusion
The WordPress Updating Failed error can be an annoying issue, but with the right troubleshooting steps, you can resolve it without much hassle.
By checking for server issues, increasing the PHP memory limit, deactivating conflicting plugins and themes, ensuring correct file permissions, and performing manual updates, you can keep your WordPress site running smoothly.
By following these steps and keeping your WordPress installation up to date, you’ll ensure that your site remains secure, efficient, and free from the dreaded updating errors.
