WordPress File Permission Errors and Security Best Practices
Error message:
Unable to create directory / Could not create directoryWordPress needs write access to certain directories (wp-content/uploads, wp-content/cache) to function properly. If file permissions are wrong, you’ll get errors when uploading media, installing plugins, or updating WordPress.
Common Causes
- Incorrect file ownership (should be www-data or your web server user)
- File permissions too restrictive (can't write to wp-content/uploads)
- SELinux or AppArmor blocking write access
- Hosting environment restrictions on file creation
- WordPress trying to write to a read-only filesystem
