Encountering a “Failed to open stream: No such file or directory” error in WordPress can be problematic, especially for beginners or people starting with WordPress.

The error indicates that WordPress is attempting to load a specific file but cannot locate it.

It often points to a misconfiguration, missing file, or permission issue.

In this guide, we’ll break down the most common causes of this error and provide clear steps to troubleshoot it.

The “Failed to open stream: No such file or directory” error is a common issue that WordPress users encounter. It usually indicates a problem with file or directory accessibility or permission. This error message usually appears when a script tries to open a file or directory and fails to do so.

While the message often specifies the location and line number in the script where the error occurred, it can still be cryptic for those not familiar with WordPress architecture.

This issue is essentially the system’s way of saying, “Hey, I tried to find this file to execute something important, but I couldn’t find it. Help me!”

WordPress’ ‘Failed to open stream’ error can be caused by a number of factors which are worth investigating before trying to fix the problem.

Common Causes of “Failed to Open Stream” in WordPress

1. Incorrect File Paths: The most common reason is an incorrect or misspelled file path. If the code tries to call a file that doesn’t exist in the specified directory, the system can’t find it, leading to the error.

2. Missing Files or Directories: If a required file or directory was accidentally deleted, or not uploaded correctly, the script won’t be able to locate it.

3. Permissions Issues: File permissions dictate who can access certain files. If permissions are incorrectly set, WordPress may not be able to read or execute the necessary file.

4. Corrupted .htaccess: The .htaccess file controls site access and redirection rules. A misconfigured or corrupted .htaccess can prevent WordPress from accessing files.

5. Server Configuration Issues: In some cases, server misconfigurations or limitations can prevent certain files from loading, especially if you’re on cheap shared hosting.

We discussed earlier that the error can be caused by a variety of reasons, and the error message will differ depending on whether the error is caused by a particular file and the location of that file.

When this warning is displayed by PHP, it means that the file or directory could not be found. You thus need to search for the script and find out which file or directory it’s trying to access.

For exemple, imagine you’ve got a script which calls a plugin. Syncing the files would be impossible if the plugin was not installed correctly or if the folder was not written accurately.

Verify the file and folder spelling and check if it has not been deleted. If a plugin or theme appears to be the issue, try uninstalling and reinstalling it.

If this fix doesn’t work, the problem might be linked to your .htaccess file

The .htaccess file is like a set of rules that your website follows when it talks to the server. Think of it like a GPS telling drivers (data and files, in this case) where to go. If the GPS starts giving out bad directions, drivers might go the wrong way.

If the .htaccess file has wrong or confusing “directions,” the server can get confused and might not find the files it’s supposed to show when someone visits your website.

When this happens, you might see the “Failed to open stream” error, which is basically the server’s way of saying, “Hey, I couldn’t find what you’re looking for!”

You must then go to the Settings » Permalinks page within your WordPress admin and select the ‘Save changes’ button to regenerate the .htaccess file.

This should fix your failed to open stream error. If it doesn’t, keep reading!

When the error message is followed by ‘Permission denied’, WordPress is unable to access the file or directory referenced in the code.

For this problem to be fixed, you need to inspect and correct WordPress files and directory permissions.

To do so, click the File Manager link under your cPanel menu or open your favorite FTP client.

Look for the file or directory that is mentioned in the error message.

After you have located it, right-click it and select ‘Change Permissions’.

Check that the Read, Write, and Execute boxes are checked.

In most cases, this will solve the problem and make everything work again.

The “Failed to open stream: No such file or directory” error in WordPress can come from incorrect file paths, missing files, permissions issues, and server limitations.

By systematically troubleshooting each potential causeyou can often resolve the error effectively.

If all else fails, enable debugging mode or consult your hosting provider for further assistance. Following these steps ensures that you’re covering the most common causes and solutions, allowing you to keep your WordPress site running smoothly.

This error means that WordPress or a plugin/theme is trying to access a file or directory that doesn’t exist in the specified location. It usually indicates a misconfigured file path, missing files, or permission issues.

The error message often includes the file path, which can indicate if a specific plugin or theme is responsible. To troubleshoot, you can temporarily deactivate plugins or switch to a default theme and check if the error persists.

To prevent this error in the future, keep your plugins, themes, and WordPress core updated and avoid deleting files or directories that are integral to plugins or themes.
