Fix WordPress Failed to Write File: Quick Solutions
Such an issue happens when WordPress or another web application tries to upload a file but cannot save it because of permission issues. Here’s how to fix it.
Here are several steps you can take to troubleshoot and resolve this issue:
- Make sure the server has enough available disk space to store the uploaded file. If the disk is full or nearly full, the server may not be able to write new files, resulting in this error.
- Verify that the directory where the uploaded files are stored has the correct file permissions. The directory should typically have write permissions (chmod 755 or chmod 777, depending on the server configuration) to allow the webserver to write files to it.
- PHP temporarily stores uploaded files in a designated directory before transferring them to their final location. Ensure that the temporary directory specified in the PHP configuration (upload_tmp_dir directive) exists and has the correct permissions for PHP to write files to it.
- If the uploaded file is large, it may exceed the upload limits configured in PHP. Increase the upload_max_filesize, post_max_size, and max_execution_time directives in the PHP configuration (php.ini file) to allow larger files to be uploaded.
- Review the server configuration to ensure that there are no restrictions or limitations on file uploads imposed by server settings, security modules, or firewall rules.
- Check the server error logs for any additional information or error messages that may provide insight into the cause of the upload failure. Sheet in search of disk space errors, file permissions errors or file writing operation errors.
- Try uploading different files to see if the issue is specific to certain file types or sizes. It can help narrow down the cause of the problem.
- As a quick solution, you can upload the file using FTP or the file manager available in your hosting control panel. Bypasses the web application’s file upload functionality and may allow you to upload the file successfully.
By following these steps and addressing the possible causes of the file upload error, If you get a file upload error like Failed to write file to disk, you can find and fix the issue that’s causing your server to block file uploads.
