Are you seeing the ‘failed to open stream’ error in WordPress?

Failed to open stream error in WordPress

What Causes the ‘Failed to Open Stream’ Error in WordPress?

The ‘failed to open stream’ error occurs when is unable to load a file or resource mentioned in the website’s code.

When this happens, sometimes WordPress will continue loading your website and only show a warning message in the place where the error occurs. Other times, WordPress will show a fatal error and will not load anything else.

The message phrasing will be different depending on where the error occurs in the code and the reason for failure. It will also give you clues about what needs to be fixed.

Typically, this message will look something 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

Here is another example:

Last Error: 2023-04-04 14:52:13: (2) HTTP Error: Unable to connect: ‘fopen(compress.zlib://
/webproperties/~all/profiles?start-index=1): failed to open stream: operation failed’

Having said that, let’s take a look at how to troubleshoot and fix the ‘failed to open stream’ error in your WordPress website based on the error message. You can use these quick links to skip to a specific section:

How to Fix ‘No Such File or Directory’ Error Message

If the error message contains ‘no such file or directory,’ then you need to look in the code to figure out which file is mentioned on that particular line.

If it is a media file, then you can try reuploading it to the media library.

If it is a plugin or theme file, then this means that the plugin or theme files were either deleted or not installed correctly.

You will simply need to deactivate and reinstall the theme or plugin in question to fix the error. If it is a plugin, please see our guides on how to deactivate WordPress plugins and how to install a WordPress plugin.

You can also read our guide on how to deactivate WordPress plugins when you’re unable to access wp-admin if you cannot log in to WordPress.

If it is a theme, please see our guides on how to delete a WordPress theme and how to install a WordPress theme.

However, WordPress may also be unable to locate the files because of a missing .htaccess file in your root folder.

In this case, you need to go to the Settings » Permalinks page in your WordPress site admin and just click on the ‘Save Changes’ button to regenerate the .htaccess file.

How to Fix ‘Permission Denied’ Error Message

If the error message is followed by ‘permission denied,’ then this means that WordPress does not have the right permission to access the file or directory referenced in the code.

To fix this, you need to check WordPress files and directory permissions and correct them if needed. You may also want to see if your temporary folder is missing and if it’s causing this error.

How to Fix ‘Operation Failed’ Error Message

Finally, some WordPress plugins load scripts from third-party sources like Google Analytics, Facebook APIs, Google Maps, and more.

Some of these third-party APIs may require authentication or might have changed the way developers can access them. A failure to authenticate or an incorrect access method will result in WordPress failing to open the required files.

To fix this, you will need to contact the plugin author for support. They should be able to help you fix the error.

Other Ways to Fix WordPress ‘Failed to Open Stream Error’

If none of these tips help you resolve the issue, then you can try a few additional methods.

At times, loading files that exceed the available memory can lead to the ‘failed to open stream’ error. You can try increasing the PHP memory limit in your wp-config.php file to see if it solves the problem.

Occasionally, a plugin or theme can conflict with WordPress core files and cause this error. To troubleshoot, temporarily deactivate all plugins and switch to a default theme like Twenty Twenty-Four.

If the error disappears, then you can start reactivating plugins one by one to pinpoint the culprit.

Additionally, try using WordPress debug mode and error logs to gather more information about the error and pinpoint the location in the code where it occurs.

In rare cases, corrupted WordPress core files themselves might be causing the error. If you’ve tried all the previous solutions and the error persists, consider reinstalling your WordPress software.

    I would also like to add that sometimes some FTP clients change the size of letters from uppercase to lowercase or vice versa. Linux machines are case sensitive. That is, the file may actually be there, but it may have different capital letters, and for Linux it is already a different file than what it is looking for.

    Three of my WP sites are hosted on the same hosting. All of them are giving the same error:

    Warning: require(/home/selfsbsr/public_html/pulse/wp-includes/post.php): failed to open stream: Permission denied in /home/selfsbsr/public_html/pulse/wp-settings.php on line 166

    Warning: require(/home/selfsbsr/public_html/pulse/wp-includes/post.php): failed to open stream: Permission denied in /home/selfsbsr/public_html/pulse/wp-settings.php on line 166

    Fatal error: require(): Failed opening required ‘/home/selfsbsr/public_html/pulse/wp-includes/post.php’ (include_path=’.:/opt/alt/php56/usr/share/pear:/opt/alt/php56/usr/share/php’) in /home/selfsbsr/public_html/pulse/wp-settings.php on line 166

    Note that these three sites are single sites and NOT part of Multisite Network. They do NOT share databases or directories.
    All they have in common is the host.
    I’ve tried to resolve this by resetting permissions of all the files and directories, disabling plugins by renaming folders of each of em, disabling theme by renaming its folder. I’ve checked the htaccess file. Nothing is out of the ordinary. And yet, I can’t do anything bring it back up.
    What should be the probable cause?
