Common Causes of the Failed To Open Stream Error


What exactly is the ‘failed to open stream’ error? This malfunction occurs when WordPress is unable to load a file mentioned in the code script.

Sometimes the page will seem to continue loading and will present a warning message. In other cases, users may see a fatal error and the WordPress page won't load at all.

So what are some common roots of the ‘failed to open stream’ error? Usually, the message identifies the problem and narrows down the steps needed to fix it.

It may say operation failed, permission denied, or no such file in the directory.

Depending on the root cause, the message should lead to the source of the problem. The error message may look like this:

Warning: require(/home/website/wp-includes/load.php): failed to open stream: No such file or directory in /home/website/wp-settings.php on line 19
Fatal error: require(): Failed opening required ‘/home/website/wp-includes/load.php’ (include_path=’.:/usr/share/php/:/usr/share/php5/’) in /home/website/wp-settings.php on line 19

Or users could get this kind of ‘failed to open stream‘ error:

Last Error: 2018-04-04 14:52:13: (2) HTTP Error: Unable to connect: open(compress.zlib:// failed to open stream: operation failed’

Understanding the reasons why the error occurs can help to manage it efficiently. Below are the possible methods for fixing the issue.

How to Correct the 'Failed To Open Stream' Error

The process of fixing the error will depend on the root cause.

The error message can vary. So the first step in correcting the issue is to read the error message carefully.

It will pinpoint the source of the problem. Then you can take corresponding steps to resolve it.

The following section of this article considers how to fix 4 causes of the 'failed to open stream' error. They are:

1. no such file or directory

2. permission denied

3. plugin errors

4. operation failed

How to Fix No Such File Or Directory


If you get this error message, check which file is indicated on that specific line in the code.

Having identified the corrupted file, see if the spelling of the name is correct. It could be as simple as that.

If the file in question is a theme or a plugin, try to reinstall it. Deactivating and reactivating it usually solves the issue.


Another possible cause could be a missing .htaccess file in the root folder. The solution is to recreate the .htaccess file.


To do that, log in to the WordPress Dashboard. In the menu on the left select Settings> Permalinks.

Make the necessary changes and don't forget to save them. This should fix the error.

How to Fix Permission Denied


This error message means that WordPress requires a permission to access the file or directory indicated in the code.

It's not uncommon to have different permissions for certain website files. It enables owners to allow access only to specific users.


This setup can be the root cause of the Permission denied error. Changing the permissions setup will fix the problem.

After logging into your WordPress website via an FTP client, locate the root folder. Then right-click on it and choose File Permissions.


All folders should have a permission of 744 or 755.

Before applying the modifications, check the boxes ‘Recurse into subdirectories’ and ‘Apply to directories only’. Finally click on Save/OK.

Next, check the permissions setup for the files. The correct value is 644 or 640.

How to Fix Plugin Errors


There are different types of plugin issues that can be the cause of the ‘failed to open stream’ error.

As mentioned earlier, it may be necessary to reinstall certain plugins. This simple step could fix the problem.

Other plugins use scripts from third-party sources, such as Google APIs. This needs to be set up correctly to avoid authentication and access problems.


Many WordPress theme contributors are not official WordPress developers. Some plugins haven't had thorough testing and may not provide smooth integration.

For those experiencing issues with a particular plugin, try contacting its developer. However, be aware that they could charge for extra support.

Support forums are a great source of tips and advice on how to fix plugin errors.

Another idea is to visit the plugin’s website. Search through the FAQs to see if other users have encountered the same problem.

Most likely you're not the first person facing the error.

How to Fix Operation Failed


In this case, the root problem is a failure to authenticate or an incorrect access method.

This malfunction can be caused by plugins that load scripts from third-party APIs. Some may be using sources like Google Analytics, Facebook APIs, Google Maps, etc.

There may be a specific procedure or authentication needed to access them.

To fix this error it’s necessary to contact the developer. They’ll be able to look at the problem in detail and offer an appropriate solution.
