Why Failed to Open Stream Error Happens?

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

This error occurs when WordPress is incapable of loading a file mentioned in your website code.

Warning: require(/mysite/wp-includes/file.php): failed to open stream: No such file or directory in /mysite/wp-settings.php on line 32

Here’s how to troubleshoot and fix the ‘failed to open stream’ error in WordPress.

Fixing Failed to Open Stream Error in WordPress

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.

‘no such file or directory’ message

Search for the script and find out which file or directory it’s trying to access.

Verify the spelling. If it’s correct, then it could be that it was deleted.

As an example, imagine you’ve got a script which calls a certain plugin. Syncing the files would be impossible if the plugin was not installed correctly. If a plugin or theme seems to be malfunctioning, try removing and reinstalling it.

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

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’.
