What Is the “Failed to open stream: No such file or directory” error?

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.

How to Troubleshoot ‘Failed to Open Stream’ Issues

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.

Option 1: The ‘No Such File or Directory’ Message

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

Option 2: Troubleshooting The Open Stream Error With The .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.

Option 3: Permission Denied Error

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.


A “Failed to open stream: No such file or directory” error doesn’t have to be the end of your WordPress site. By carefully following these troubleshooting steps, you can rectify the problem and get your site back up and running smoothly.
